Dodecanedioic dihydrazide is widely used as a crosslinking agent in polymer chemistry, particularly in the production of polyurethane and epoxy resins. It enhances the thermal stability and mechanical strength of these materials, making them suitable for high-performance coatings, adhesives, and composites. In the textile industry, it serves as a key component in flame retardant finishes, providing fabrics with improved fire resistance. Additionally, it is employed in the synthesis of specialty chemicals, such as hydrazide-based compounds, which are utilized in pharmaceuticals and agrochemicals for their reactive properties. Its ability to form strong bonds with various substrates also makes it valuable in surface modification and functionalization processes.
