Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Phototransformation in air

The atmospheric oxidation half-life of 2-aminobenzenesulphonic acid was estimated using the level III multimedia model. It was estimated that the substance is not persistent in air medium as the half life period of 2-aminobenzenesulphonic acid in air is only 0.071 days. This indicates that 2-aminobenzenesulphonic acid is rapidly photo-transformed in air.  

OVERALL OH Rate Constant =0.000000000023cm3/molecule-sec at 25 degC.

Hydrolysis

The Hydrolysis rate constant of 2-aminobenzenesulphonic acid is estimated to be 0.0000000000231544 cm3/molecule-sec. at half life of 5.543 Hrs.The estimated half life of the substance indicates that the substance is moderately hydrolysable.

Phototransformation in water

No experimental data available. As this study is not a standard information requirement in REACH and there is no indication from the CSA on the need to investigate further the fate and behaviour of the substance (Annex X requirement), no further testing is considered necessary.

Phototransformation in soil

No experimental data available. As this study is not a standard information requirement in REACH and there is no indication from the CSA on the need to investigate further the fate and behaviour of the substance (Annex X requirement), no further testing is considered necessary.
