Used as a reagent in organic synthesis, particularly in the development of heterocyclic compounds. It serves as a thiocyanating agent for aromatic ketones and participates in cyclization reactions to form biologically active sulfur-containing heterocycles. Commonly applied in medicinal chemistry for modifying molecular structures to enhance pharmacological properties. Also utilized in the preparation of intermediates for pharmaceuticals and agrochemicals due to its reactivity with nucleophiles. Shows utility in research settings for probing reaction mechanisms involving thiocyanate transfer.
