Description

3-Diethylaminopropylamine is a versatile aliphatic diamine with a tertiary amine and a primary amine functionality. This bifunctional nature makes it a valuable intermediate for synthesizing a wide range of specialty chemicals, including surfactants, corrosion inhibitors, and epoxy curing agents. It is essential for manufacturers in the agrochemical, pharmaceutical, and polymer industries seeking to develop performance-enhancing additives and active ingredients.

Application

• Epoxy Curing Agent Intermediate: A key building block for manufacturing modified amine-based hardeners, imparting flexibility and improved chemical resistance to cured epoxy systems.
• Surfactant & Detergent Production: Used to synthesize cationic and amphoteric surfactants for personal care products, industrial cleaners, and fabric softeners.
• Corrosion Inhibitor Formulation: Serves as a precursor for filming amines and other inhibitors used in water treatment and oilfield applications to protect metal surfaces.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) and pesticide molecules due to its reactive amine groups.
• Polymer Modification: Acts as a chain extender or crosslinking agent in polyurethane and polyurea formulations.
• Gas Treating Agent: Utilized in the production of compounds for carbon dioxide (CO₂) and hydrogen sulfide (H₂S) scrubbing in natural gas processing.
• Chelating Agent Synthesis: A starting material for manufacturing ligands used in metal ion sequestration and catalysis.

Quality Control

Our 3-Diethylaminopropylamine is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and amine value titration, to ensure it meets precise specifications and is free from critical impurities. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, containers should be kept tightly sealed when not in use to prevent absorption of atmospheric moisture and carbon dioxide. Recommended storage temperature is 15-25°C.
