3Dimethylaminopropylamine

3-Dimethylaminopropylamine, commonly abbreviated as DMAPA, is an organic diamine used as a chemical building block in various industrial syntheses. Its molecular formula is C5H14N2, reflecting a primary amino group at one end of a three-carbon chain and a tertiary dimethylamino group at the other end, giving the structural motif NH2-CH2-CH2-CH2-N(CH3)2. This combination makes DMAPA a bifunctional amine with both primary and tertiary amine character.

DMAPA is produced and handled as an intermediate in the manufacture of surfactants, surfactant precursors, and certain polymeric and pharmaceutical intermediates. It serves as a precursor to quaternary ammonium compounds and other amine-functional materials used in detergents, emulsifiers, and specialty cleaners. In epoxy resin chemistry, it can act as a reactive curing agent or as a starting material for more complex amine-based curing systems. The compound is typically used in controlled, industrial settings and is often supplied as a neat liquid or in solution.

Safety and handling are important considerations. DMAPA is a corrosive and irritant to skin, eyes, and the respiratory tract. It should be used with appropriate personal protective equipment, including gloves and eye protection, and only under within-hood or well-ventilated conditions. It is reactive with acids and can form hazardous salts; storage should be in a tightly closed container, protected from moisture and incompatible oxidizing agents. Proper disposal procedures should be followed in accordance with local regulations.
