Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and antiviral agents. Its hydrazine functionality allows for facile derivatization, enabling the formation of hydrazone or azole rings, which are common structural motifs in bioactive molecules. Commonly employed in medicinal chemistry for scaffold modification and library generation in drug discovery programs. Also utilized in the preparation of heterocyclic compounds with potential anticancer and antimicrobial activities.
