It is one of a group of neutral derivatives of primary amines; its formula is RN&dbnd;C&dbnd;O, where R may be an alkyl or aryl group; an example is 2,4-toluene diisocyanate. Any compound containing the isocyanato functional group.
In other words;
Isocyanate is the functional group of atoms –N=C=O (1 nitrogen, 1 carbon, 1 oxygen), not to be confused with the cyanate functional group which is arranged as –O–C≡N.
