Used as a key intermediate in the synthesis of bioactive molecules, particularly in the development of antitumor and antimicrobial agents. Its hydrazide functionality allows for easy derivatization into various heterocyclic compounds such as 1,3,4-oxadiazoles and Schiff bases, which exhibit enhanced pharmacological activity. Commonly employed in medicinal chemistry research for designing new quinoline-based drugs targeting cancer and infectious diseases. Also utilized in coordination chemistry as a ligand to form metal complexes with catalytic or biological properties.
