Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In contact with water 2 -ethylhexanoyl chloride will hydrolyse rapidly.
Key value for chemical safety assessment
Additional information
Parent combound CAS 760 -67 -8:
The substance has been determined to degrade spontaneously in contact with aqueous media. No rate constant or half-life could be determined experimentally by Method 111 of the OECD Guidelines for testing of Chemicals, 12 May 1981. At pH 4 and 0 °C, the hydrolysis was significantly greater than 50 % prior to analysis of the initial sample (SafePharm Laboratories, 2003). The hydrolysis products are 2-ethylhexanoic acid and hydrochloric acid.
Hydrolysis product (CAS 149 -57 -5):
In accordance with column 2 of REACH Annex VII, the study does not need to be performed if the substance is readily biodegradable or inorganic. 2-Ethylhexanoyl chloride hydrolyses rapidly and forms 2-ethylhexanoic acid and hydrochloric acid. 2-Ethylhexanoic acid is readily biodegradable (EKO LAB, 1998), while hydrochloric acid 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.
