'''Isosianat''' adalah [[gugus fungsi]] dengan rumus kimia R–N=C=O. [[Senyawa organik]] yang mempunyai 2 gugus isosianat disebut diisosianat. Diisosianat diproduksi bersama dengan [[poliol]] untuk produksi [[poliuretana]], sebuah [[polimer]].

== Reaktivitas ==
=== Reaksi dengan nukleofil ===
Isosianat adalah [[elektrofil]] dan mereka reaktif terhadap berbagai macam [[nukleofil]] termasuk [[alkohol]], [[amina]], dan bahkan air. Reaksi isosianat dengan alkohol menghasilkan ikatan [[uretana]]:
:ROH + R'NCO → ROC(O)N(H)R' (R dan R' adalah gugus [[alkil]] atau [[aril]])
