Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of sulfathiazole, a sulfonamide antibiotic. It also serves in the development of other biologically active compounds, including antifungal, anti-inflammatory, and anticancer agents. Its structure supports derivatization for use in agrochemicals and dyes. Commonly employed in research for constructing heterocyclic compounds due to its reactive amino and hydroxyl functional groups.
