Description of key information
The substance 2-aminobenzenesulphonic acid is not persistent in air medium as the half life period of 2-aminobenzenesulphonic acid in air is only 0.071 days which does not exceeds the criteria of 2 days.
Key value for chemical safety assessment
- Half-life in air:
- 0.71 d
- Degradation rate constant with OH radicals:
- 0 cm³ molecule-1 s-1
Additional information
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 = 0.000000000023 cm3/molecule-sec at 25 degC.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
