‌

‌N,N-dimethyl-1,3-diaminopropane is in the form of a colorless liquid‌‌.

N,N-dimethyl-1,3-diaminopropane (DMAPA) has a variety of uses, mainly including the following aspects:
As an intermediate for industrial preparation‌: DMAPA is an important intermediate, widely used in the industrial preparation of lubricants, for example‌1. It is also used as a raw material for the preparation of coagulants and should have antiseptic properties‌.

‌Used in the synthesis of pesticides and surfactants‌: DMAPA can react with coconut methyl ester, methyl oleate, methyl stearate, etc. to produce corresponding alkylamides and propyl betaine products, which are widely used in the manufacture of civilian cleaning agents and textile softening finishing agents, and are also raw materials for the manufacture of cosmetics, such as shampoo, bath foam and other daily chemical products‌.

‌Application in electroplating and textile industries‌: DMAPA can be used as an auxiliary agent in the electroplating industry‌. At the same time, it can also be used in the manufacture of textile treatment agents and paper treatment agents‌.

‌ Used in the synthesis of dyes and ion exchange resins ‌: DMAPA is used as an organic synthesis intermediate for the preparation of dyes, ion exchange resins, etc. ‌ For example, it can be used to synthesize D213 ion exchange resin ‌. ‌ Epoxy resin curing agent and accelerator ‌: Since DMAPA has both tertiary and primary amine groups, it has the functions of epoxy resin curing agent and accelerator, and is mainly used for laminated products and cast products ‌. ‌ Other uses ‌: DMAPA is also used to produce flocculants, cypermethrin, etc. ‌, as an additive for oil and cyanide-free electroplating zinc, fiber and leather treatment agents and fungicides, etc. ‌ In addition, in the field of chemical synthesis, it can also be used as a good chemical reactant to promote the combination between molecules, thereby increasing the reaction rate and product yield ‌. ‌ In summary, N,N-dimethyl-1,3-diaminopropane has a wide range of applications in many fields and is a very important chemical substance.
