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).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
