Used as a curing agent or crosslinking promoter in polyurethane systems, enhancing mechanical strength and thermal stability of elastomers and coatings. Also serves as an intermediate in agrochemical synthesis, particularly in the production of herbicides and plant growth regulators. Its hydrazide structure allows it to act as a chelating agent in metal-catalyzed reactions, improving catalyst efficiency. Additionally, employed in specialty adhesives and sealants where controlled reactivity and improved adhesion are required.
