In the vast landscape of chemical intermediates, 3-Dimethylaminopropylamine (DMAPA), identified by CAS number 109-55-7, plays a pivotal role across numerous industrial sectors. This aliphatic amine is characterized by its colorless, transparent liquid appearance and a high degree of purity, typically exceeding 99.5%. Its unique chemical structure, boasting both primary and tertiary amine groups, makes it an indispensable building block for a wide array of products, from essential personal care ingredients to high-performance industrial resins. For procurement specialists and research scientists, understanding DMAPA's properties and sourcing channels is vital for operational success.

DMAPA’s physical and chemical characteristics are central to its utility. It remains a liquid across a broad temperature range, with a melting point of -60°C and a boiling point of 133°C. Its density is approximately 0.81 g/mL at 25°C, and it is soluble in both water and common organic solvents, facilitating its integration into various chemical processes. The presence of two reactive amine groups allows DMAPA to participate in a multitude of reactions, including condensation, acylation, and nucleophilic additions.

The industrial applications of DMAPA are extensive. In the personal care industry, it is a foundational ingredient for synthesizing amphoteric surfactants, such as Cocamidopropyl Betaine (CAPB). CAPB is widely used in shampoos, body washes, and cosmetics for its mild cleansing action, lathering properties, and ability to condition skin and hair. The demand for these consumer products directly translates into a strong market for high-purity DMAPA. Sourcing DMAPA from trusted manufacturers ensures the quality and efficacy of these formulations.

Industrially, DMAPA is a key component as an epoxy resin curing agent. Its amine groups react with epoxy resins to create strong, cross-linked polymer networks, vital for adhesives, coatings, and composite materials that require excellent durability, chemical resistance, and thermal stability. The efficiency of DMAPA in this role makes it a preferred choice for manufacturers in the plastics and materials science sectors. Companies often seek to buy DMAPA from suppliers in China for competitive pricing and consistent supply.

Furthermore, DMAPA serves as an intermediate in the production of ion-exchange resins used in water purification and other separation technologies. It is also utilized in the synthesis of dyes, bactericides, and as a treatment agent for textiles and leather. Its role extends to the agrochemical industry as a precursor for certain pesticides, highlighting its broad applicability. Manufacturers focusing on chemical intermediates often rely on DMAPA sourced from specialized producers.

When procuring DMAPA, key specifications to consider include its CAS number (109-55-7), the minimum assay (≥99.5%), and its physical appearance (colorless transparent liquid). Safety is also a critical aspect; DMAPA is flammable and requires proper handling and storage. Reputable suppliers, particularly those in China like NINGBO INNO PHARMCHEM CO.,LTD., provide comprehensive technical data sheets and adhere to strict quality control measures, ensuring a reliable supply of this essential chemical for diverse industrial needs.
