2-Amino-5-chlorobenzoic acid Use and Manufacturing

Methods of Manufacturing

To a solution of 5-chloro-2-nitrobenzoic acid (20 g, 110 mmol) in ethanol was added freshly activated raney nickel (2 g). The mixture was stirred overnight at room temperature under hydrogen atmosphere. The solution was filtered through celite and evaporated under reduced pressure to yield 16 g (96percent) of white SOLIDS. 1H NMR (DMSO-D6) : d 6.77 (d, J = 8.9 Hz, 1H), 7.24 (DD, J= 2.9, 8.9 Hz, 1H), 7.62 (d, J= 2.9 Hz, 1H), 8.7 (b, 3H); EIMS: 170 (M-H).

Uses

5-Chloroanthranilic Acid is a chlorinated derivative of anthranilic acid. 5-Chloroanthranilic Acid is a metabolite of the pesticide Chlordimeform. 5-Chloroanthranilic Acid is used in the preparation of disease-modifying antirheumatic drugs (DMARDs).
