化合物简介
2-Bromobenzonitrile belongs to a group of ortho-substituted bromobenzenes that have varying hepatotoxicity effects in the presence of rat liver microsomes in vitro. 2-Bromobenzonitrile is also used as a starting material to synthesize novel benzothiophene derivatives that were found to exhibit antibacterial and antifungal activity. It is commonly employed in reactions that require an electron-rich species to carry out nucleophilic substitution (or addition) reactions.

生产方法及用途
生产方法
可用尿素和二溴醛为原料生产,也采用对羟基苯甲醛、对羟基苯甲酸为原料生产。 溴苯腈及其盐和酯是有一定内吸活性的触杀性除草剂,主要用在禾谷类、亚麻、大蒜、玉米、洋葱、高粱和新播种的草皮,芽后防除草苗期阔叶杂草。与其他除草剂混用,可扩大除草谱。
