Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

There are no investigations on the degradation in surface waters or sediments of the test substance. Nevertheless, based on results of a biodegradation study (OECD guideline 301C), 4-nitrotoluene-2-sulphonic acid was assessed to be poorly biodegradable (3 % after 28 days). Therefore, biotic degradation is not expected in any further surface water or sediment simulations studies. Consequently, 4-nitrotoluene-2-sulphonic acid is assessed to be persistent in the environment.
