Used as a chemical building blockintermediate in organic synthesis particularly for preparing heterocyclic compounds. It is also used in pharmaceutical agrochemical and specialty chemical synthesis.

Mainly used to introduce a carbamothioyl (thiourea-related) group into organic molecules. It reacts with amines and other nucleophiles to form useful intermediates for further synthesis.

O-Ethyl carbonisothiocyanatidate also called ethoxycarbonyl isothiocyanate It is a moisture-sensitive light-yellow oil and should be handled under appropriate laboratory conditions.
