Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Although itself not readily biodegradable, the substance has been shown to rapidly hydrolyse to N-phenylmaleamic acid (CAS No. 555-59-9) which is itself predicted to be readily biodegradable (EPISUITE QSAR modelling), it is indicated that this subsequent biodegradadation proceeds via breakdown into maleic acid (CAS No. 108-31-6) and aniline (CAS No. 62-53-3) which are known to be biodegradable.

This substance has a biodegradable potential in soil. (Half-Live = 720 h)

The hydrolysis product (Maleanilic acid) has also a biodegradable potential in soil (Half-Life = 720 h)

QSAR result by Bcfwin (v2.15) as follows: Predicted fate in a wastewater treatment facility 74.5% degradation.

So, this substance is estimated as biodegradable under STP conditions.
