Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Phototransformation in air
Parent compound butyryl chloride (CAS 141-75-3): After evaporation or exposure to air, the substance will be slowly degraded by photochemical processes.
This estimation refers to dry air. In mist, rain, droplets and aerosols hydrolysis will be the major fate process of the acid chloride due to the short half-life in aqueous solutions.Therefore this estimate may be of low relevance.
Hydrolysis product butyric acid (CAS 107-92-6): After evaporation or exposure to air, the substance will be slowly degraded by photochemical processes.
Hydrolysis
Parent compound butyryl chloride (CAS 141-75-3): Butyryl chloride is determined to hydrolyse rapidly to butyric acid and HCl.
Hydrolysis product butyric acid (CAS 107-92-6): According to Regulation (EC) 1907/2006, Annex VIII, Section 9.2.2.1, Column 2, a study does not need to be performed if the substance is readily biodegradable or inorganic. Butyryl chloride hydrolyses rapidly and forms butyric acid and HCl. Butyric acid is readily biodegradable, while HCl is 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.
