Isocyanate is the functional group with the formula RN=C=O. Organic compounds that contain an isocyanate group are referred to as isocyanates. An organic compound with two isocyanate groups is known as a diisocyanate. Diisocyanates are manufactured for the production of polyurethanes, a class of polymers.[1] Isocyanates should not be confused with cyanate esters and isocyanides, very different families of compounds. The cyanate (cyanate ester) functional group (ROCN) is arranged differently from the isocyanate group (RN=C=O). Isocyanides have the connectivity R-NC For price, specification and other details please contact us.
