Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Phototransformation in air
The atmospheric oxidation half-life of 4-aminobenzene-1,3-disulphonic acid was estimated using the level III multimedia model. It was estimated that the substance is persistent in air medium as the half life period of 4-aminobenzene-1,3-disulphonic acid in air is only 3.1 days. This indicates that 4-aminobenzene-1,3-disulphonic acid is not rapidly phototransformed in air.
OVERALL OH Rate Constant =0.0000000000052 cm3/molecule-sec at 25 degrees C
Hydrolysis
The Hydrolysis rate constant of 4-aminobenzene-1,3-disulphonic acid was estimated to be 0.0000000000052004 (5.2004 E-12) cm3/molecule-sec at a half life of 24.681 hrs. The estimated half life indicates that 4-aminobenzene-1,3-disulphonic acid would be slowly hydrolysable.
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.
