3-Dimethylaminopropylamine

3-Dimethylaminopropylamine (CAS 109-55-7 ), commonly abbreviated as DMAPA, is a bifunctional diamine used as a reactive intermediate and process chemical across specialty chemical manufacturing. It combines a primary and a tertiary amine in a single molecule, making it a building block for synthesizing surfactants, polymers, and active ingredients for various industrial applications. In personal care, it is the key reactant in producing cocamidopropyl betaine, the amphoteric surfactant found in shampoos, body washes, and mild cleansing formulations for consumer use. Pharmaceutical manufacturers use it as an intermediate in synthesizing active compounds and as a pH-buffering agent in formulation chemistry to ensure stability and efficacy of the final product. In polymer chemistry, it functions as a curing agent and chain extender for epoxy systems and polyurethane coatings. It also serves as a corrosion inhibitor precursor and stabilizer additive. This chemical is supplied as a clear to slightly yellow liquid in standard drum and IBC quantities, with bulk tanker options available for high-volume buyers and large-scale operations. Technical grade is the most common commercial specification, though higher-purity grades are available to meet pharmaceutical intermediate requirements and specific manufacturing standards. Buyers should confirm amine content and water specification when sourcing for surfactant synthesis, where consistent purity directly affects downstream yield and overall product quality.
