Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

pKa at 20°C:
10.35

Additional information

No data is available on the substance itself. However, a peer-reviewed article provides a pKa value on an analogue.

Based on chemical similarity (isomers with different position of the alkyl group), no significant difference is anticipated with the present dossier substance, so the read-across is considered justified for a key study.
