Used as a key intermediate in the synthesis of heterocyclic compounds, particularly in the preparation of thiourea derivatives and sulfides. It serves as a selective reagent in organic transformations where controlled sulfur transfer is required. Commonly applied in pharmaceutical manufacturing for building blocks involving sulfur-containing functional groups. Also utilized in agrochemical synthesis due to its reactivity and stability under various reaction conditions. Its tert-butyl group enhances steric control in asymmetric synthesis, improving selectivity in complex molecule construction.
