性质描述: 无色或微黄色叶状结晶。熔点67℃，沸点66-68℃（0.27kPa）。易溶于乙醇和苯，不溶于水。
生产方法: 由对溴甲苯经下列反应制得：在光照条件下，将溴从液面下滴加至105℃的对溴甲苯中，滴加前期的温度为105-110℃。后期的温度为135℃。加完后温度慢慢升至150℃，然后加入碳酸钙粉末和水搅匀，加热回流15min进行水解。再进行水蒸气蒸馏，将馏出液冷却，滤出对溴苯甲醛结晶。
用途: 医药和染料的中间体。

应用
4-Bromobenzaldehyde is widely utilized as an intermediate for the preparation of agrochemicals, pharmaceuticals and other organic compounds. It is used as a precursor and reacts with sulfamethoxazole to prepare Schiff?’s base, 4-[(4-Bromo-benzylidene)-amino]-N-(5-methyl-isoxazol-3-yl)-benzene sulfonamide, which can be used for the photo stability of polyvinyl chloride (PVC). It plays an important role in palladium-catalyzed mono- and bis-arylation of 3,4-(ethylenedioxy)thiophenes. It is employed in a cross-coupling study with potassium vinyltrifluoroborate.

备注
Keep container tightly closed in a dry and well-ventilated place. Incompatible with strong bases, strong oxidizing agents and strong reducing agents.
