Ammonium dodecanedioate is primarily used in the production of high-performance polymers, particularly polyamides and polyesters. Its application in polymer synthesis contributes to the creation of materials with enhanced thermal stability, mechanical strength, and chemical resistance. These properties make it valuable in manufacturing automotive parts, industrial coatings, and specialty fibers. Additionally, it serves as an intermediate in the synthesis of corrosion inhibitors and lubricants, which are essential in protecting metal surfaces and improving the efficiency of mechanical systems. Its role in the development of biodegradable plastics also supports environmentally friendly material solutions.
