Used in the synthesis of pharmaceuticals, particularly as an intermediate in the production of sulfonamide-based antimicrobial agents. It also serves as a building block in the development of agrochemicals, including herbicides and fungicides, due to its reactive functional groups. Its heterocyclic structure makes it valuable in creating compounds with biological activity, and it is employed in research for designing new drug candidates targeting various diseases. Additionally, it finds use in the preparation of dyes and specialty chemicals where nitrogen-sulfur containing rings enhance stability and performance.
