Description of key information
Based on its chemical structure, trichloroacetyl chloride is expected to hydrolyse very quickly in water. Indeed, acyl halides, i.e. R-C(=O)-halogen {Cl, Br, I, F} (where R is a carbon or halogen), react readily with water to yield the parent acid and hydrogen halide. In the case of trichloroacetyl chloride hydrolysis degradation products are hydrochloric acid (CAS# 7647-01-1) and Trichloroacetic acid (CAS# 76-03-9). The model HYDROWIN v2.00 indicates that the hydrolysis half-lives are less than 10 minutes (or faster).
No experimental data is available on the fate and behavior of trichloroacetyl chloride in the environment. As the substance is hygroscopic, even if it has a non negligible volatility, it is expected to be rapidly degraded to hydrochloric acid and trichloroacetic acid after release into the environment. Therefore, the environmental profile of the substance is based on the properties of these degradation products.
Hydrochloric acid being an inorganic substance, biodegradability tests and logKow measurement are not applicable.
Trichloroacetic acid has been assessed in the OECD SIDS initial assessment program (Assessed in SIAM 5, 28/10/1996, Published in March 2001). In this assessment, trichloroacetic acid is considered miscible in water with a low potential of volatilization. It is non biodegradable and has a low bioaccumulation potential. These conclusions are supported by the QSAR estimation reported in the Endpoint Study Record of the present dossier for logKow and biodegradability in water.
To conclude, the main environmental target compartment of trichloroacetyl chloride will be water under the form of trichloroacetic acid. The justification of the read across approach between these two substances is available in the attached document of the relevant Endpoint Study Record.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
