Conclusions:
Biodegradation half-life of test substance Benzenesulfonic acid, 5-amino-2-(phenylamino)- in soil was estimated to be 75 days (1800 hrs)
Executive summary:

The half-life period of Benzenesulfonic acid, 5-amino-2-(phenylamino)- (CAS No. 91 -30 -5) in soil was estimated using Level III Fugacity Model by EPI Suite version 4.1 estimation database (EPI suite, 2016). If released into the environment, 82.3% of the chemical will partition into soil according to the Mackay fugacity model level III. The half-life period of Benzenesulfonic acid, 5-amino-2-(phenylamino)- in soil is estimated to be 75 days (1800 hrs). Based on this half-life value of Benzenesulfonic acid, 5-amino-2-(phenylamino)-, it is concluded that the chemical is not persistent in the soil environment and the exposure risk to soil dwelling animals is moderate to low.
