Description of key information

This substance is easily hydrolyzed in alkaline water and transformed into N-phenylmaleamic acid (CAS No.555-59-9). The transformed substance is anticipated to be transformed into maleic acid (CAS No.108-31-6) and aniline (CAS No.62-53-3) which substances are known to be biodegradable. 

Key value for chemical safety assessment

Half-life for hydrolysis:
1.4 h
at the temperature of:
30 °C
