Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 94-97-3, name is 5-Chloro-1H-benzo[d][1,2,3]triazole, This compound has unique chemical properties. The synthetic route is as follows., Quality Control of 5-Chloro-1H-benzo[d][1,2,3]triazole
To a solution of 5-chloro-1H-benzotriazole (1 g) and sodium acetate (1g) in acetic acid was added bromine (2 g). After 10 days at room temperature, the mixture was treated with a saturated solution sodium thiosulfate, neutralized with a saturated solution of sodium bicarbonate and extracted with ethyl acetate. The organic phase was washed with brine, dried over anhydrous sodium sulfate, filtered and the filtrate concentrated under reduced pressure to afford a residue that was purified by semi- preparative liquid chromatography to afford 4-bromo-5-chloro-1 /-/-benzotriazole as an off-white solid (213 mg, 14%). MS (ES): M/Z [M+H]=232. 1H NMR: (400 MHz, DMSO-dbeta): 7.58 (d, J =8.7 Hz, 2H) and 7.91 (d, J =8.7 Hz, 1H).
According to the analysis of related databases, 94-97-3, the application of this compound in the production field has become more and more popular.
