| | 2-Nitrobenzoic acid Usage And Synthesis |
| Chemical Properties | off-white powder | | Uses | NH2-protecting reagent. | | Uses | 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. | | Definition | ChEBI: A nitrobenzoic acid carrying the nitro substituent at position 2. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 56, p. 5924, 1991 DOI: 10.1021/jo00020a040
Tetrahedron Letters, 35, p. 219, 1994 DOI: 10.1016/S0040-4039(00)76515-4 | | General Description | Yellowish white crystals with an intensely sweet taste. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | 2-Nitrobenzoic acid is incompatible with strong oxidizing agents. Also incompatible with strong bases. May react with cyanides . | | Health Hazard | ACUTE/CHRONIC HAZARDS: When 2-Nitrobenzoic acid is heated to decomposition it emits very toxic fumes. | | Fire Hazard | Flash point data concerning 2-Nitrobenzoic acid are not available, however, 2-Nitrobenzoic acid is probably combustible. | | Purification Methods | 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).
