n-Butyl Isocyanate CAS 111-36-4 is a simple aliphatic isocyanate used as an intermediate in organic synthesis and specialty chemical manufacture. The reagent is reactive toward nucleophiles such as alcohols and amines to form urethanes and ureas, enabling its use in small-molecule derivatization, polymer modification and the synthesis of tailored intermediates. Because of its reactivity, n-Butyl isocyanate is handled under controlled conditions and is most commonly used in solution or converted rapidly into less reactive derivatives or prepolymers.
