Mosher's acid chloride

WebAn acyl chloride (or acid chloride) is an organic compound composed of a chlorine atom attached to an acyl group in organic chemistry. An acyl group is a functional group defined by the molecular formula of RCO. Thus, the acid chloride family is part of a larger organic family known as acyl halides.
