In the chemical manufacturing sector, intermediates are the backbone of production, enabling the synthesis of a vast array of complex and essential products. Among these, 3-Dimethylaminopropylamine, commonly known as DMAPA and identified by CAS number 109-55-7, holds a significant position. This aliphatic amine is a colorless, transparent liquid recognized for its high purity and bifunctional nature, making it indispensable in applications ranging from personal care products to advanced industrial materials. For businesses looking to source this critical intermediate, understanding its properties and the advantages of procurement from manufacturers in China is key.

DMAPA’s chemical structure, featuring both a primary and a tertiary amine group, endows it with versatile reactivity. It typically exhibits a minimum assay of 99.5% and a very low water content, ensuring its suitability for sensitive chemical syntheses. Its physical state as a liquid, with a relatively low melting point (-60°C) and a moderate boiling point (133°C), allows for ease of handling and processing in industrial settings. Solubility in water and organic solvents further enhances its utility as a reaction medium or component.

One of the most prominent applications of DMAPA is its role as a key intermediate in the production of surfactants, particularly amphoteric surfactants like Cocamidopropyl Betaine (CAPB). CAPB is a staple ingredient in many personal care products, including shampoos, body washes, and cosmetics, where it provides gentle cleansing, rich lather, and conditioning effects. The consistent demand for these consumer goods necessitates a reliable supply of high-quality DMAPA from manufacturers who can meet stringent purity requirements.

In the industrial sector, DMAPA serves as a critical component in the formulation of epoxy resins. As an epoxy curing agent, it facilitates the cross-linking reaction that transforms liquid epoxy resins into strong, durable, and chemically resistant thermoset polymers. These materials are essential for high-performance adhesives, protective coatings, and advanced composites used in aerospace, automotive, and construction industries. Companies often seek to buy DMAPA to ensure the desired mechanical and thermal properties of their final epoxy products.

Beyond these major uses, DMAPA is also integral to the production of ion-exchange resins for water treatment, and it acts as an intermediate for dyes, bactericides, and textile treatment agents. Its versatility makes it a valuable commodity for chemical suppliers and distributors worldwide. Sourcing from China offers an attractive proposition for many companies due to competitive pricing and significant production capacities. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. are recognized for their commitment to quality, offering DMAPA that meets international standards for purity and performance.

When considering the purchase of DMAPA, it is essential to focus on suppliers who can provide detailed product specifications, including CAS number (109-55-7), assay, appearance, and safety data. Given its flammability, proper handling and storage protocols are paramount. By partnering with reputable manufacturers, businesses can ensure a stable supply of this vital intermediate, enabling the efficient production of a wide range of consumer and industrial goods.
