3-Dimethylaminopropylamine

3-Dimethylaminopropylamine (CAS 109-55-7), commonly abbreviated as DMAPA, is a bifunctional diamine used as a reactive intermediate and process chemical.

Where is 3-Dimethylaminopropylamine used?

• Surfactant synthesis: building block combining a primary and a tertiary amine in one molecule
• Personal care: key reactant in cocamidopropyl betaine for shampoos, body washes and mild cleansing formulations
• Pharmaceuticals: intermediate for active compounds and pH-buffering agent in formulation chemistry
• Polymer chemistry: curing agent and chain extender for epoxy systems and polyurethane coatings
• It also serves as a corrosion inhibitor precursor and stabilizer additive.
• Catalyst for Knoevenagel condensation.

Good to know: Buyers should confirm amine content and water specification when sourcing for surfactant synthesis, where consistent purity directly affects downstream yield and product quality.

Typical specification

• Minimum purity specification of 98% (GC).

Storage, packaging and handling

• Reacts with 1,2-dichloroethane with explosion hazard.
• Store fireproof, separately from strong oxidants, strong acids, food and animal feed, and keep tightly closed.
• Must not be transported with food and feedstuffs.
