"Isocyanate is the functional group with the formula –N=C=O. Organic compounds that contains an isocyanate group are referred to as isocyanates. An isocyanate that has two isocyanate groups is known as a diisocyanate. Diisocyanates are manufactured for reactions with polyols in the production of polyurethanes. The largest use of isocyanates in industry involves the production of polymers. Polymers of common isocyanates are used in the manufacture of foams, paints, lacquers and in electrical insulation."
"Not to be confused with isocyanates are cyanates and isocyanides. Cyanate is another functional group, which is arranged as –O–C≡N. Isocyanides have the connectivity R-N≡C. Their behavior is very different from isocyanates."
