4-溴-1,2-二氨基苯可以通过1,2-二氨基苯的乙酰化反应以及随后的溴化和碱水解获得。 4-Bromo-o-phenylenediamine, is used as an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuff.4-Bromo-1,2-diaminobenzene can be obtained from 1,2-diaminobenzene via acetylation followed by bromination and alkaline hydrolysis. 4-Bromo-1,2-diaminobenzene can be used as a precursor for preparing fluorescent dipolar quinoxaline derivatives, which can find applications as potential emissive and electron-transport materials. It can also be used in the synthesis of 6-bromo-2-methylbenzimidazole.
