Description of key information

The chemical 3-acetamido-5-amino-4-hydroxybenzenesulphonic acid  is not persistent in air medium as the half life period of 3-acetamido-5-amino-4-hydroxybenzenesulphonic acid  in air is only 0.16 days.

OVERALL OH Rate Constant =0.0000000001cm3/molecule-sec.

Key value for chemical safety assessment

Half-life in air:
0.16 d
Degradation rate constant with OH radicals:
0 cm³ molecule-1 s-1

Additional information

The atmospheric oxidation half life of 3-acetamido-5-amino-4-hydroxybenzenesulphonic acidwas estimated using level III multimedia model it indicates that3-acetamido-5-amino-4-hydroxybenzenesulphonic acidis not persistent in air medium as the half life period of 3-acetamido-5- amino-4-hydroxybenzenesulphonic acidin air is only 0.16 days. From this it is concluded that 3-acetamido-5-amino-4-hydroxybenzenesulphonic acidis rapidly phototransformed in air.
