Used primarily as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals and agrochemicals. Its structure serves as a building block for heterocyclic compounds exhibiting antimicrobial, antifungal, and anti-inflammatory properties. Commonly employed in the development of isothiazolone-based preservatives, which are effective in controlling microbial growth in industrial water systems, paints, and personal care products. Also utilized in research for designing novel enzyme inhibitors and functional materials due to its electron-rich aromatic core.
