A carbamoyl chloride is the functional group with the formula RNC(O)Cl. The parent carbamoyl chloride, HNCOCl is unstable, but many N-substituted analogues are known.  Most examples are moisture sensitive, colourless, and soluble in nonpolar organic solvents. An example is dimethylcarbamoyl chloride (m.p. −90 °C and b.p. 93 °C). Carbamoyl chlorides are used to prepare a number of pesticides, e.g. carbofuran and aldicarb.
