Used primarily as a key intermediate in the synthesis of pharmaceuticals and agrochemicals. It participates in ring-opening and substitution reactions, making it valuable in constructing heterocyclic compounds. Commonly employed in the development of herbicides and fungicides due to its ability to enhance bioactivity in final products. Also utilized in medicinal chemistry for designing compounds with antimicrobial and antiviral properties. Its reactivity allows for easy functionalization, enabling its use in various condensation and cycloaddition reactions during drug discovery.
