Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and analgesics. It serves as a building block for pyridine and piperidine-based bioactive molecules, which are common in drugs targeting neurological disorders. Its hydrazide functionality allows for easy conversion into heterocyclic compounds such as 1,3,4-oxadiazoles and 1,3,4-thiadiazoles, which are important scaffolds in medicinal chemistry. Also employed in the preparation of selective enzyme inhibitors and receptor ligands due to its favorable binding properties and structural flexibility.
