Used as an intermediate in the synthesis of heterocyclic compounds, particularly in the preparation of benzothiazole and related fused-ring systems. It serves in agrochemical manufacturing, contributing to the development of certain pesticides and plant growth regulators. Also applied in pharmaceutical research for designing sulfur- and nitrogen-containing bioactive molecules, including potential anticonvulsant and antimicrobial agents. Its structure supports chelation, making it useful in coordination chemistry for metal ion sensing or catalysis.
