用途
使用
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.
一般的な説明
Yellowish white crystals with an intensely sweet taste.
製法・合成法
純化方法
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.]
