Additional information

Phototransformation in air:

The atmospheric oxidation half-life of3-acetamido-5-amino-4-hydroxybenzenesulphonic 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 of3-acetamido-5-amino-4-hydroxybenzenesulphonic acid in air is only 0.16 days. This indicates that3-acetamido-5-amino-4-hydroxybenzenesulphonic acid is rapidly phototransformed in air.

Hydrolysis:

The Hydrolysis rate constant of 3-acetamido-5-amino-4-hydroxybenzenesulphonic acid is estimated to be 0.0000000001012748 cm3/molecule-sec at half life of 1.267 Hrs.The estimated half life of the substance indicates that the substance is rapidly 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.
