Diethylenetriamine (CAT: R063765) is a linear polyamine with the molecular formula C₄H₁₃N₃, consisting of two primary amine groups and one secondary amine group connected by ethylene linkages. It is a colorless to pale yellow, hygroscopic liquid with a characteristic amine-like odor. DETA is widely used as a curing agent in epoxy resin systems, a chelating agent in coordination chemistry, and an intermediate in the synthesis of corrosion inhibitors, surfactants, and textile additives. Its strong nucleophilicity and ability to form stable complexes with metal ions make it valuable in water treatment, lubricant formulation, and polymer modification research.
