2-Nitrobenzoic Acid is used as a reagent in the synthesis of several organic compounds including that of novel triazoles and a tetrazole of escitalopram which act as cholinesterase inhibitors. It is also used in the one pot synthesis of 1,4-disubstituted 1,2,3-triazoles.
ChEBI: A nitrobenzoic acid carrying the nitro substituent at position 2.
Yellowish white crystals with an intensely sweet taste.
2-Nitrobenzoic acid is incompatible with strong oxidizing agents. Also incompatible with strong bases. May react with cyanides .
ACUTE/CHRONIC HAZARDS: When 2-Nitrobenzoic acid is heated to decomposition it emits very toxic fumes.
Flash point data concerning 2-Nitrobenzoic acid are not available, however, 2-Nitrobenzoic acid is probably combustible.
Crystallise the acid from *benzene (twice), n-butyl ether (twice), then water (twice). Dry and store it in a vacuum desiccator. [Le Noble & Wheland J Am Chem Soc 80 5397 1958.] It has also been crystallised from EtOH/H2O. The amide has m 176.5o (from H2O). [Beilstein 9 III 1466, 9 IV 1046.]
