Carbon Tetrachloride was executed for crimes against the ozone layer.
Deserved? Probably not.

Carbon Tetrachloride (Carbon Tet for short, or Tetrachloromethane, named herself Katharin Martin) is a major/main character in Chemical Culture. She is mostly known for being a former firefighter, a successful and talented dry-cleaner and Chloroform's older sister. She was created in 1820, making her one of the oldest Organochlorides, C. Tetrachloride is 10 years older than Chloroform and 19 years older than her brother Dichloromethane. C. Tetrachloride was executed for "crimes against the ozone layer" in 2010.

Personality and relationships

Carbon Tetrachloride had a dark sense of humour and would make jokes about controversial topics and eating people's livers. She was unable to feel anger, never held a grudge against anyone and was very calm besides the times when she bursted into laughter. C. Tetrachloride threatened everyone with stealing and eating their livers when they slightly disagreed with her. She got off to making humans suffer by causing them organ damage. Often seen calling people and other Chemicals "degenerates". She refuses to use the name "Tetrachloromethane" because she thinks that IUPAC is like "the Illuminati for Chemical folks". She did not want to be organic and her father Carbon Disulphide is responsible for this. Beginning in the 1860s, until 1950, she was under the influence of him. She moved next to Chloroform and DCM's house after the 1950s where she lived until 1970.

Carbon Tetrachloride with Tetrachloroethylene, 1926

Carbon Tetrachloride pretended to be nice and protective towards humans when she was a doctor and a firefighter because she wanted to be a nice Chemical. It was, again, C. Disulphide who made her accept herself and stop "trying to be who she cannot be". She faked being French, spoke French with a British accent and called herself random French names. She was actually ashamed of being old and always lied about being 8 years younger than Chloroform. C. Tetrachloride is very fluent in Portuguese and Spanish due to working in Latin America in the 1930s.

Her brothers (Dichloromethane and Chloromethane) meant nothing to her while Chloroform was her "dearest" due to being both her younger sister and her mother. C. Tetrachloride even threatened Chloromethane. She has been called "Carbon Tit(s)" by DCM because he wanted to touch her titties. Chloroform calls her "Necatorina"[necator means "murderer" in Latin, how lovely]. Chloroform defends her more than anyone else. Unlike Chloromethane, DCM and even Chloroform, she did not like Methanol, she called Methanol a "cougar" for DCM. She has called her brothers "degenerates". Despite being a former dry-cleaner and a pioneer in dry-cleaning, C. Tetrachloride despised dry-cleaners but she was kinder to Tetrachloroethylene whom she spent her early life with and taught dry-cleaning. Trichloroethane I, who was also executed for "crimes against the ozone layer", never called her by the name, instead, she called C. Tetrachloride "The Liver-eating Hellspawn Organochloride Goddess/Mother". Trichloroethane allegedly had a crush on her.


Carbon Tetrachloride is a tall woman with very long, straight dark blue hair and dark red eyes. She often curled her hair or cut it very short during her career. She loved to style her hair into 4 braids, just like Chloroform had done for a longer time. She has very pale skin and an unusually muscular build for a Chemical. Her face looks very serious and masculine which gives humans the false impression of seriousness and "professionality"[she was actually a professional at work but not in the personality manner]. She never smiled with her teeth showing to humans because she did not want them to see her fangs. She smells sweeter than Chloroform but not as strong as Chloroform and she is proud of her deceptive odour.

C. Tetrachloride wore work-appropriate but sometimes kind of "revealing" clothes. She could be seen in hyper-feminine or hyper-masculine clothing at any time of the day, she had no preference in clothing except for her preference to wear black/dark-coloured clothes, and often wore black gloves. She always wore the same type of blue-red striped long socks and black leather shoes with heels. She does not wear any underwear and most of her clothes were taken from Chloroform's wardrobe and restyled to fit herself. Her uniform coat was red, unlike her siblings' dark blue coats.

Early life and career

Carbon Tetrachloride was first created from Hexachloroethane in 1820 and named "Protochloride of Carbon". Her relation to Chloroform was first reported in 1839 after the discovery that Chloroform could also spawn her. She worked as an anaesthetist/doctor around the 1860s under the name "Bichloride of Carbon" or "Chlorocarbon", after seeing her sister Chloroform killing too many patients during anaesthesia. C. Tetrachloride was successful and stronger than her sister, she told Chloroform to quit anaesthesia several times for the sake of the patient's safety. Her work did not gain enough attention and eventually, she left the field a short time later. Beginning in 1922 to the 1940s, C. Tetrachloride also had another short but more successful career in medicine which she rarely ever mentioned; she worked as a "doctor" to fight against parasites in humans and farm animals. She introduced Tetrachloroethylene to this field in 1925. Both were very successful on their own in fighting parasites.

Carbon Tetrachloride as a firefighter, late 1910s

C. Tetrachloride became a firefighter in 1910 and worked as one until the 1960s when she used her heavy vapours to suffocate the flames. She hired her cousin Trichloroethylene and sister Chloroform as her assistants to work in cold weather as cold weather stopped her vapours. She was forced to retire because the phosgene from the decomposition of her vapours killed many humans during duty and C. Tetrachloride was replaced by Halons who worked more safely.

Carbon Tetrachloride has worked in textile and general cleaning industries under the names "Katharin", "Carbon-Tet" and "Benzinoform", and opened her first dry-cleaner in the 1890s as an opposition to the dominant Hydrocarbons in this industry. She was very successful in the dry-cleaning industry and introduced Trichloroethylene and Tetrachloroethylene into dry-cleaning in the 1930s. Then C. Tetrachloride entirely retired from this industry in the 1960s around when Tetrachloroethylene overthrew Trichloroethylene.

She had a good understanding of mechanics and loved to clean and repair machinery. She worked as a hairdresser in England from 1903 to 1913 and served to high society women. She also had a very short, experimental career in refrigeration like many other people in the Organohalides family. C. Tetrachloride also made lava lamps and sold them from 1965, until 1970 which she describes as "the beginning of the end" for her.

Later years, execution and legacy

Humans noticed Carbon Tetrachloride's homicidal potential as early as the 1900s when she was working as a hairdresser but no one took any action since she had already gained humans' trust. She had killed many humans during duty and this led to the US government retiring her from all close-contact work with humans in 1970, this was "the beginning of the end" for her. Until 1986, C. Tetrachloride worked in agriculture together with her father C. Disulphide. In 1987, humans discovered that she had committed "crimes against the ozone layer", she was banned from doing any work after an order by humans. After 1987, she was not allowed outside ever and was kicked out of The Council. C. Tetrachloride survived the 1996 Halocarbon executions which her refrigeration consultant son Trichlorofluoromethane did not. Her other children Chlorotrifluoromethane and Dichlorodifluoromethane were only warned and retired.

Humans carried out another large-scale Halocarbon executions for the same "crimes against the ozone layer" reason in 2010. This order included those who were forgiven in the 1996 order and got warnings. Carbon Tetrachloride and her CFC children Chlorotrifluoromethane and Dichlorodifluoromethane were executed following this order.


Even after her execution, there had been controversies involving C. Tetrachloride and the ozone layer. Humans stated that they "should have acted earlier" about Carbon Tetrachloride. She was idolised by many humans and Chemicals because of her hard work and interesting history and properties. An online fandom grew nearly 10 years after the execution of C. Tetrachloride.


Carbon Tetrachloride has been involved in various controversies during her life. Despite being a great worker, she tended to physically harm humans who worked with her. She had issues with humans who consumed alcohol and had killed humans who simply stayed in the room as her after they consumed alcohol. At first, she was ashamed of these since it was not a thing that she controlled and tried so hard to keep her image as a preferred and safe Chemical, but ever since humans acknowledged her effects on their livers and took measurements against her, she realised that it was impossible to suppress "your true nature" as a Chemical and she came loose. She "ate" humans' livers and lethally caused kidney damage.

Ozone layer

Just like any other Chemical who has the Volatility power, C. Tetrachloride emits non-flammable and heavy vapours which she used to extinguish fires. It was discovered in 1985 or 1987 that her vapours were damaging the ozone layer.
