Executive summary:

3-amino-4-hydroxy-5-nitrobenzenesulphonic acid is found to be slightly irritating to rabbit's skin at 500 mg/24H of concentration. Since this substance is a structural analog (read across) to the target chemical, 3-amino-2-hydroxy-5-nitrobenzenesulphonic acid, having more than 92.6 % similarity and thus the toxicity effect can be considered for the target substance as well. Thus it can be infered that 3-amino-2-hydroxy-5-nitro benzene sulphonic acid is skin irritant in category 2.
