3 -aminobenzoic acid is an organic carboxylic acid, which is used for the preparation of azo dyes. In addition to the 3- aminobenzoic acid, two more positionally forms exist: the anthranilic acid (o- amino benzoic acid ) and 4-aminobenzoic acid (p- aminobenzoic acid ).
Production and representation
3 -aminobenzoic acid may be obtained by the reduction of 3- nitrobenzoic acid. Suitable reducing agents are, for example elemental zinc in hydrochloric acid or hydrazine.
3 -aminobenzoic acid exhibits low toxicity. In addition, no evidence of reproductive toxicity, mutagenicity and carcinogenicity was found.
