Used primarily as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of certain herbicides and insecticides. Its reactivity allows for the introduction of isothiocyanate functional groups into more complex molecules, facilitating the development of compounds with targeted biological activity. It also finds use in the preparation of thiourea derivatives, which are important in medicinal chemistry and crop protection agents. Due to its electrophilic nature, it participates in various condensation and addition reactions useful in organic synthesis.
