Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The half life period of 2-aminobenzenesulphonic acid in water is 15 days and based on this value it can be concluded that the chemical is not persistent in water medium since the half  life is less than the threshold of 60 days (to qualify the chemical as persistent).

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

The half life period of 2-aminobenzenesulphonic acid in water is 15 days and based on this value it can be concluded that the chemical is not persistent in water medium since the half life is less than the threshold of 60 days (to qualify the chemical as persistent). Also the diffusion percentage of 2-aminobenzenesulphonic acid in water medium is 31%. This coupled with the dilution of water shall result in ready biodegradabililty of the chemical.
