Used primarily as an intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds and pharmaceuticals. It serves as a building block in the development of hydrazide-based drugs, which may exhibit antimicrobial, antifungal, or anti-inflammatory properties. Also employed in research settings for modifying peptides and creating specialized reagents. Its reactivity with carbonyl groups makes it valuable in condensation reactions for forming hydrazones, useful in both analytical chemistry and drug design.
