Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceuticals and agrochemicals. Its structure supports the creation of isothiazole-based derivatives with antimicrobial, antifungal, and anti-inflammatory properties. Commonly employed in research settings to design new heterocyclic compounds with potential therapeutic applications. Also utilized in the preparation of functional materials where sulfur- and nitrogen-containing heterocycles are required for specific reactivity or stability.
