  • Applications

    N,N'-Dimethyl-1,3-propanediamine (CAS 111-33-1) is typically used as a building block in the production of specialty chemicals, including surfactants, coatings, and resin systems. It is commonly evaluated as an epoxy-curing accelerator or catalyst, leveraging the tertiary amine sites to influence cure kinetics. The compound can serve as an intermediate for further chemical modification and, as a diamine with two tertiary nitrogens, may function as a ligand in metal complexation or as a starting material for functional additives such as corrosion inhibitors or cleaning/formulation aids, depending on local regulations and formulation constraints.
