Used in pharmaceutical research as a key intermediate for synthesizing bioactive molecules, particularly in the development of kinase inhibitors and antitumor agents. Its hydrazine functionality allows for easy derivatization, enabling the formation of hydrazone or azole structures that enhance binding to biological targets. Also explored in medicinal chemistry for designing compounds with anti-inflammatory and antimicrobial properties. Additionally, serves as a building block in heterocyclic synthesis due to its fused ring system and reactive side chain.
