Used primarily as a key intermediate in the synthesis of fluorinated pharmaceuticals and agrochemicals. Its structure allows for selective functionalization in heterocyclic compound formation, especially in the development of triazole and indole-based drugs. Commonly employed in medicinal chemistry for constructing bioactive molecules with enhanced metabolic stability and binding affinity. Also utilized in the preparation of dyes and fluorescent probes due to its aromatic hydrazine functionality, which participates in condensation reactions to form hydrazones.
