Used as a key intermediate in the synthesis of fluorinated pharmaceuticals and agrochemicals. Its structure allows for selective functionalization in heterocyclic compound formation, particularly in the development of triazole and pyrazole derivatives with biological activity. Commonly employed in medicinal chemistry for constructing nitrogen-containing rings that enhance metabolic stability and binding affinity in drug candidates. Also utilized in the preparation of dyes and fluorescent probes due to its electron-modulating properties.
