Description

3-Dimethylaminopropylamine (CAS NO 109-55-7) is a versatile bifunctional organic compound featuring both a tertiary amine and a primary amine group. This structure makes it a critical intermediate for synthesizing a wide range of specialty chemicals and polymers. It is essential for manufacturers in the pharmaceutical, agrochemical, water treatment, and personal care industries seeking to produce high-performance surfactants, curing agents, and active pharmaceutical ingredients.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing local anesthetics, antispasmodics, and other active pharmaceutical ingredients (APIs).
• Epoxy Curing Agent & Hardener: Used as a catalyst and cross-linking agent in epoxy resin systems for coatings, adhesives, and composites.
• Surfactant & Detergent Production: Serves as a precursor for betaine-type amphoteric surfactants used in personal care products and industrial cleaners.
• Corrosion Inhibitor: Formulated into products for water treatment and metalworking fluids to protect industrial systems.
• Agrochemical Synthesis: Intermediate in the production of herbicides, fungicides, and plant growth regulators.
• Polyamide & Polyurethane Resins: Acts as a chain extender or curing agent in the production of specialty polymers.
• Gas Treating Agent: Used in formulations for the removal of acid gases like CO₂ and H₂S in natural gas processing.
• Textile & Leather Auxiliaries: Employed in the manufacture of softening agents, dyeing auxiliaries, and finishing chemicals.
