Description of key information

According to structural properties, hydrolysis is not expected/probable. The substance was determined to be hydrolytically stable at pH 4, 7 and 9.

Key value for chemical safety assessment

Additional information

In a guideline study conducted in compliance with OECD 111 the hydrolysis of the substance as a function of pH was tested. No hydrolysis at pH 4, 7 and 9 was determined (MITI, Japan 1994).
