3-Dimethylaminopropylamine, commonly abbreviated as DMAPA and bearing the CAS number 109-55-7, is a vital aliphatic amine that serves as a cornerstone in many chemical manufacturing processes. Recognized for its colorless, transparent liquid form and high purity, DMAPA is a critical intermediate used in sectors ranging from personal care to industrial materials. Understanding its chemical properties and industrial applications is crucial for procurement managers and chemical engineers seeking reliable sourcing partners.

As an aliphatic amine, DMAPA possesses a unique molecular structure with both a primary and a tertiary amine group. This bifunctionality makes it highly reactive and suitable for a broad spectrum of chemical syntheses. Typically, DMAPA is supplied with an assay of 99.5% or higher, ensuring consistent performance and quality in its intended applications. Its physical properties, including a melting point of -60°C and a boiling point of 133°C, combined with its solubility in water and organic solvents, facilitate its handling and processing in various industrial environments.

The applications of DMAPA are diverse and significantly impact consumer and industrial markets. In the personal care industry, DMAPA is a fundamental building block for amphoteric surfactants, such as Cocamidopropyl Betaine (CAPB). These surfactants are widely incorporated into shampoos, body washes, and cosmetics, providing gentle cleansing, rich lather, and conditioning properties. The consistent demand for these products means a reliable supply of high-quality DMAPA is essential.

Industrially, DMAPA is highly valued as an epoxy resin curing agent. It reacts with epoxy resins to form robust, cross-linked polymer networks, which are critical for the production of high-performance adhesives, durable coatings, and advanced composite materials used in demanding applications like aerospace and automotive manufacturing. The efficiency of DMAPA in promoting this curing process makes it a preferred intermediate for resin formulators.

Beyond these primary uses, DMAPA also functions as an intermediate in the synthesis of dyes, bactericides, and as a treatment agent for textiles and leather. Its utility extends to the production of ion-exchange resins used in water treatment and purification processes. Furthermore, it finds application as an additive in fuels and lubricants. For industries requiring a consistent and cost-effective supply of this versatile chemical, sourcing from manufacturers in China, such as NINGBO INNO PHARMCHEM CO.,LTD., is often a strategic choice due to their production capabilities and competitive pricing.

When procuring DMAPA, attention to specifications like CAS number (109-55-7), assay (≥99.5%), and proper packaging is important. Safety considerations, including its flammability, are also paramount. By partnering with reputable suppliers who prioritize quality and adhere to safety standards, companies can ensure a stable supply of this essential chemical intermediate, thereby supporting the efficient production of a wide range of valuable products.
