For businesses across various sectors requiring chemical intermediates, securing a reliable and high-quality source is paramount. 3-Dimethylaminopropylamine (DMAPA), identified by CAS number 109-55-7, is a critical aliphatic amine intermediate that finds extensive use in the production of surfactants, epoxy resins, and numerous other specialty chemicals. Understanding the essential specifications and how to effectively source DMAPA is key to successful procurement. This guide focuses on helping procurement managers and chemists identify reliable suppliers, particularly those based in China.

DMAPA is valued for its chemical structure, featuring both primary and tertiary amine functionalities, which makes it a versatile reactant. Its typical appearance is a colorless to slightly yellow liquid, with a characteristic amine odor. High purity is a significant factor for industrial applications, and DMAPA is commonly available with an assay of 99.5% or higher, ensuring consistent performance in downstream processes. Low water content, typically below 0.5% (often around 0.02% in quality products), is another important specification that indicates product integrity.

The applications of DMAPA are diverse and impactful. In the personal care industry, it is a vital precursor for synthesizing amphoteric surfactants like Cocamidopropyl Betaine (CAPB), which are essential components in shampoos, body washes, and cosmetics for their mildness and foaming capabilities. When you need to buy DMAPA for these formulations, prioritizing high purity ensures the quality of the final consumer products.

Industrially, DMAPA serves as a highly effective curing agent for epoxy resins. These resins are integral to adhesives, coatings, and composite materials due to their excellent strength, chemical resistance, and thermal stability. DMAPA's amine groups react with the epoxide rings to form a cross-linked polymer network. For manufacturers of epoxy systems, consistent availability and competitive pricing of DMAPA are crucial for production efficiency and cost management. Many companies actively search for DMAPA suppliers in China to leverage cost advantages.

Beyond these major applications, DMAPA is also employed in the production of ion-exchange resins, which are critical for water treatment and purification processes. It acts as an intermediate for dyes, bactericides, and is used as a treatment agent in the leather and textile industries. Its role in the synthesis of agrochemicals further broadens its market significance.

When sourcing DMAPA, it's important to look for manufacturers who can provide comprehensive technical data sheets (TDS) and safety data sheets (MSDS). These documents detail product specifications, handling procedures, and safety precautions. Given its flammable nature, proper storage and handling are essential. Reputable suppliers will also offer robust packaging solutions, such as 165kg drums or IBCs, to ensure product integrity during transit.

For businesses seeking to purchase DMAPA, China has emerged as a leading global manufacturing hub, offering competitive pricing and significant production capacity. Companies like NINGBO INNO PHARMCHEM CO.,LTD. specialize in providing high-purity DMAPA, catering to international markets. By focusing on suppliers with a proven track record of quality control and reliable delivery, procurement professionals can secure a steady supply of this vital chemical intermediate. Whether you are looking for small quantities for research or large volumes for industrial production, understanding these sourcing aspects will help you make informed decisions and ensure the success of your manufacturing operations.
