Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Parent compound: In contact with water, the substance will hydrolyse rapidly.
Hydrolysis product pivalic acid: According to structural properties, hydrolysis is not probable.

Key value for chemical safety assessment

Additional information

In a GLP guideline study following OECD TG 111 the test material has been determined to degrade spontaneously in aqueous media. No rate constant or half-life could be determined experimentally. Pivalic acid was determined as the major hydrolysis product (SafePharm, 2003).

According to Kollig et al. (1993), Boethling & Mackay (2000) and Harris (1990), pivalic acid is generally resistant to hydrolysis because it does not contain any labile functional groups.
