PhNCO
PhNCO, short for phenyl isocyanate, is an organic compound with the formula C7H5NO. It consists of a phenyl group attached to an isocyanate functional group (-N=C=O). In its pure form it is typically a colorless to pale yellow liquid with a sharp, acrid odor. It is reactive toward moisture and various nucleophiles and is typically handled under dry, inert conditions to prevent hydrolysis and polymerization.
PhNCO is primarily used as a reactive monomer in the production of polyurethanes and related polymers. It
