Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antituberculosis agents and other nitrogen-containing heterocyclic drugs. Its hydrazine functionality allows it to participate in cyclization reactions, forming pyridine-fused rings that are common in bioactive molecules. Also employed in the preparation of agrochemicals and dyes due to its reactivity and ability to form stable derivatives. Commonly used in research laboratories for the design of novel compounds with potential antimicrobial and anticancer activities.
