Discover Aure Chemical's Premium DMAPA Supply
3-Dimethylaminopropylamine (DMAPA), also known as N,N-Dimethyl-1,3-propanediamine, is a key chemical intermediate with the CAS number 109-55-7. This colorless to pale yellow, strong-smelling diamine combines a tertiary amino group and a primary amino group, making it highly versatile in chemical synthesis. It is a critical building block, particularly in the production of surfactants for personal care products, and in the creation of durable polymers and coatings.

Application Overview
DMAPA is one of the most versatile building blocks in the specialty chemical industry. Its dual-functionality (primary and tertiary amine groups) makes it suitable for reactions that require differential reactivity, leading to a wide array of high-value products across various sectors:
Surfactants and Personal Care: DMAPA is the essential raw material for synthesizing amidoamine intermediates, which are then used to produce amphoteric surfactants like Cocamidopropyl Betaine (CAPB). CAPB is a key ingredient in shampoos, body washes, and liquid soaps for its excellent foam-boosting and mild cleansing properties.
Epoxy Curing Agents: Due to its reactive primary amine group, DMAPA is used in the manufacture of polyamides, which act as high-performance curing agents for epoxy resins in coatings, adhesives, and composites. These systems provide excellent adhesion and chemical resistance.
Polymer and Resin Production: It is used in the synthesis of ion-exchange resins and as a monomer in the production of certain polyamide resins and cationic polymers for water treatment applications (flocculants).
Catalysis: DMAPA and its derivatives can act as catalysts and hardeners in certain polymerization reactions, including some polyurethane formulations.
Corrosion Inhibitors: Its derivatives are often incorporated into formulations used as corrosion inhibitors in oil and gas production and circulating water systems.
