Used as a key intermediate in the synthesis of quinoline-based pharmaceuticals and bioactive molecules. Its hydrazine functionality allows for the formation of hydrazone derivatives, which are important in medicinal chemistry for developing antimicrobial, antiviral, anticancer, and antioxidant agents. Commonly employed in research settings to construct nitrogen-containing heterocycles with potential therapeutic activity. Also utilized in coordination chemistry as a ligand precursor for metal complexes that exhibit catalytic or biological properties. Furthermore, it serves as a reagent in analytical chemistry for detecting certain metal ions by forming colored complexes, enabling quantitative analysis in laboratory settings.
