Used primarily as a rubber vulcanization accelerator, especially in the production of synthetic rubbers like nitrile and styrene-butadiene rubber (SBR). It helps improve the curing process, enhancing the elasticity, strength, and heat resistance of the final rubber products. Also acts as a catalyst in polyurethane foam manufacturing, promoting the urea-forming reaction for consistent cell structure and improved insulation properties. Additionally, it serves as an intermediate in the synthesis of pharmaceuticals and agrochemicals due to its strong basicity and ability to form stable salts.
