3-Diethylaminopropylamine, often abbreviated as DEAPA and identified by CAS number 104-78-9, is a chemical compound of significant industrial importance. Its chemical profile is characterized by a clear, colorless to slightly yellow liquid appearance, with a distinct ammoniacal odor. Possessing a molecular formula of C7H18N2 and a molecular weight of 130.23, DEAPA is classified as an aliphatic diamine with both primary and tertiary amino functionalities. This dual amine nature is central to its primary applications, most notably as a curing agent for epoxy resins. In this capacity, DEAPA contributes to the formation of strong, chemically resistant polymer networks essential for adhesives, coatings, and other composite materials.

Beyond its role in polymer chemistry, DEAPA is recognized for its utility as a solvent, an extractant, and a key intermediate in various organic synthesis pathways. These applications span industries such as pigment manufacturing and personal care products, underscoring its versatility. The handling and use of DEAPA necessitate strict adherence to safety protocols due to its classification as an irritant to skin and eyes, and potential toxicity if inhaled or ingested. Information regarding its flammability (flash point 138°F) and reactivity with acids and oxidizers is critical for safe storage and application.

For businesses seeking to integrate DEAPA into their operations, understanding the supply chain is key. Reliable sourcing from manufacturers and suppliers, such as NINGBO INNO PHARMCHEM CO.,LTD., ensures access to high-purity material. The market for 3-Diethylaminopropylamine is robust, with numerous global players offering this essential chemical. Whether utilized for its epoxy curing capabilities or as an organic synthesis intermediate, DEAPA remains a fundamental component in modern chemical manufacturing, supporting innovation across multiple sectors.
