Used primarily as an intermediate in organic synthesis, especially in the preparation of bioactive compounds and pharmaceuticals. It serves as a building block for hydrazide-hydrazone derivatives, which exhibit antimicrobial, antifungal, and anti-inflammatory activities. Commonly employed in medicinal chemistry research to develop novel therapeutic agents, particularly in the design of compounds targeting tuberculosis and other infectious diseases. Also utilized in the synthesis of heterocyclic compounds due to its reactive hydrazide group, enabling cyclization reactions to form five- or six-membered rings important in drug development.
