Phthaloyl chloride is an organic compound with the formula C₆H₄(COCl)₂. It is one of three isomers, the better known one being terephthaloyl chloride. The third isomer is isophthaloyl chloride. All three compounds are diacid chlorides, and hence they are susceptible to reactions with water (to give back the diacids), alcohols (to give diesters), and amines to give amides or imides.
