N,N-Dimethyl-1,3-propanediamine

N,N-Dimethyl-1,3-propanediamine (DMAPA, CAS 109-55-7) is a clear, colourless liquid with a characteristic amine odour. Its molecule contains both a primary amine (-NH₂) and a tertiary amine group, enabling dual functionality in nucleophilic reactions and catalysis. With high purity (≥ 99.0%) and excellent solubility in water and most organic solvents, DMAPA serves as a key intermediate in epoxy curing, dye synthesis, electroplating, textiles, agrochemicals, and polyurethane catalysts.
