Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
The substance decomposes rapidly on contact with moisture or water. In a study on hydrolysis performed according to the OECD guideline 111, a half-life of < 2 min was determined at pH 4, 7 and 9 at ambient temperature. Identified hydrolysis products were chloride, sulphite and sulphate. They will ionise in aqueous environments to form environmentally ubiquitous ionic species..
Additionally hydrolysis of the substance was investigated in the gas phase and depending on humidity half-lives of 1.4 minutes (74% relative humidity) to 5.9 minutes (28% relative humidity) were obtained.
Tests on biodegradation and bioaccumulation are technically not feasible as the substance reacts fast with water and the reaction products are inorganic.
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.
