Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Half life period of 3-acetamido-5-amino-4-hydroxybenzenesulphonic acid  in Soil was observed to be 75 days.Based on these half life values it is concluded 3-acetamido-5-amino-4-hydroxybenzenesulphonic acid is not readily biodegradable (persistent) in soil.

Key value for chemical safety assessment

Half-life in soil:
1 800 h
at the temperature of:
25 °C

Additional information

The PBT Profiler & EPI Suite has estimated that 3-acetamido-5-amino-4-hydroxybenzenesulphonic acid is expected to be found predominantly in soil and its persistence estimate is based on its availability in this medium. Its half-life in soil, 1800 hrs (75 days). This exceeds the EPA criteria of >= 2 months (and <= 6 months). Therefore, 3-acetamido-5-amino-4-hydroxybenzenesulphonic acid is estimated to be persistent in the soil environment.
