5-溴-2,3-二氟苯甲醛主要用于医药、农药等领域的合成，具体用途未在提供的资料中详细说明。
医药; 农药
合成路线 1（1. 合成：633327-22-7）
产率：100%
合成条件：at 60℃; for 12 h;
实验步骤：搅拌下，向搅拌的2,3-二氟苯甲醛（XVIII）（75.0g，528mmol，1.0当量）的H 2 SO 4（565mL）溶液中，在60℃下分批加入NBS（113g，633mmol，1.2当量）。 将所得混合物在60℃下搅拌12小时。 LC / MS显示反应完成。 将反应混合物倒入冰水和石油醚（500mL）中并搅拌10mm，分离有机层并在真空下浓缩，得到cmde产物。 将残余物用柱色谱法硅胶（100％石油醚）纯化，得到5-溴-2,3-二氟苯甲醛（XIX）（120g，543.0mmol，定量收率）。 ESIMS发现C7H3BrF2O m / z 221.1（M + 1）。
