What it is Filled
A chloroformate is an ester of chloroformic acid with the general structure R-O-C(=O)-Cl, combining an organic oxy group with a reactive carbonyl chloride group.
In scope
- Chloroformate functional-group identity, organic substituent and number of chloroformate groups
- Specific member identities and their verified chemical identifiers
- Purity, grade, formulation and degradation state of material samples
- Physical properties under stated measurement conditions
- Member-specific reactivity, hazards, compatibility and regulatory constraints
Out of scope
- Manufacturing routes, plant operation and reaction procedures
- Finished products containing or made using chloroformates
- Carbonates, carbamates and other reaction products as independently modelled substances

Why it exists Filled
Enable an agent to recognise a chloroformate, resolve its specific chemical identity and condition, and assess whether a proposed use is supported by substance-specific evidence.
Distinguishing features Filled
- Require the connectivity R-O-C(=O)-Cl, with chlorine attached directly to the carbonyl carbon; methyl chloroformate provides a documented member example. [PubChem](https://pubchem.ncbi.nlm.nih.gov/compound/6586)
- Distinguish a chloroformate from an ordinary carboxylic acid chloride by the oxygen between the organic substituent and carbonyl carbon.
- Distinguish a chloroformate from a carbonate ester by the carbonyl-bound chlorine in place of a second ester oxygen substituent.
- Do not identify chloroform, a chloroacetate or an unrelated chlorinated ester as a chloroformate solely because its name or formula contains chlorine.
- Resolve the organic substituent before assigning identifiers: methyl and ethyl chloroformate are separately identified substances. [Methyl chloroformate](https://pubchem.ncbi.nlm.nih.gov/compound/6586), [ethyl chloroformate](https://pubchem.ncbi.nlm.nih.gov/compound/10928)
