N,N′-Dimethyldipropylenetriamine（Cat No.:M065335）, often abbreviated as DM-DPTA, is a linear triamine compound featuring two secondary amine groups and one tertiary amine, each separated by propylene linkers, with methyl substitutions on the terminal nitrogen atoms. This compound functions as a versatile chelating agent, corrosion inhibitor, and intermediate in the synthesis of surfactants, resins, and specialty chemicals. Its strong nucleophilicity and multiple nitrogen donor atoms make it useful in complexing metal ions and modifying polymers. It is also employed in water treatment formulations and epoxy curing systems. Proper handling is required due to its reactive amine functionality and hygroscopic nature.
