Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Hydrolytically stable; expert statement (Reimer, 2004)

Key value for chemical safety assessment

Half-life for hydrolysis:
1 yr
at the temperature of:
25 °C

Additional information

Based on the hydrolytic stability of 3-chloro-o-xylene, a regioisomer of the registered substance, and the Hammett structure-activity relationship regarding the electron donating effect of meta- and para-methyl groups on an aromatic ring, it was concluded that the registered substance would be hydrolytically stable (half-life > 1 year at 25 °C) under the OECD guideline hydrolysis test conditions (5 days at 50 ° C at pH 4, 7 and 9).
