Meaning and Definition
A toxic, colourless organic chemical compound (CCl₃OC(O)Cl), used historically in chemical warfare and as a reagent in organic synthesis.
A highly reactive and hazardous liquid, historically known as 'diphosgene' due to its similar effects to phosgene gas. It decomposes to form phosgene, making it a dangerous lachrymator, lung irritant, and potential chemical weapon.

- Confusing it with 'trichloromethyl chloroformate' is its full name; 'diphosgene' is a functional synonym, not a different substance.
FAQ
Frequently Asked Questions
No, but it decomposes into phosgene. Trichloromethyl chloroformate (CCl₃OC(O)Cl) is a liquid that breaks down to form two molecules of phosgene (COCl₂), which is a gas. Their toxic effects are similar.
Almost exclusively in advanced chemistry textbooks, historical accounts of chemical warfare (WWI), technical literature on chemical weapon disarmament, or in the safety protocols of highly specialised industrial or research chemistry.
Historically, it was named 'diphosgene' because one molecule of it was observed to produce the toxic effects equivalent to two molecules of phosgene, due to its decomposition.
In highly technical shorthand, it may be abbreviated by its molecular formula 'CCl₃OC(O)Cl' or simply referred to as 'diphosgene'. There is no common, casual abbreviation.
A toxic, colourless organic chemical compound (CCl₃OC(O)Cl), used historically in chemical warfare and as a reagent in organic synthesis.
Trichloromethyl chloroformate is usually technical (chemistry, military history, industrial safety) in register.
Trichloromethyl chloroformate: in British English it is pronounced /ˌtraɪˌklɔːrə(ʊ)ˌmɛθɪl ˌklɔːrə(ʊ)ˈfɔːmeɪt/, and in American English it is pronounced /ˌtraɪˌklɔːroʊˌmɛθɪl ˌklɔːroʊˈfɔːrmeɪt/. Tap the audio buttons above to hear it.
