3-Dimethylaminopropylamine (DMAPA, CAS 109-55-7) is a bifunctional aliphatic amine containing both a primary amine and a tertiary dimethylamino group. It is widely used as an intermediate in production of amine-based surfactants, as a building block for polymer and resin modifiers, and as a reactive component in specialty formulations requiring nucleophilic/alkaline functionality. Commercial supply is offered in industrial, technical and reagent grades, with lot-specific Certificates of Analysis to support quality control.
Storage & handling
-
Store in original, tightly closed containers in a cool, dry, well-ventilated area away from acids, halogenated oxidizers and strong oxidants.
-
Temperature control: avoid prolonged exposure above ~30 °C; store under shade or refrigerated for long-term stability if recommended by supplier.
-
Hygiene & containment: prevent release to drains; use closed transfer systems and local exhaust ventilation to control vapors.
-
PPE & emergency: use chemical-resistant gloves, goggles and appropriate respirators where ventilation is insufficient; follow SDS for spill and first-aid measures.
-
Inventory practice: maintain lot traceability, rotate stock per COA and retain SDS/technical documents with incoming shipments.
Application
- Surfactant intermediate and quaternary ammonium precursor
Used to produce amine-based surfactants and tertiary-amine intermediates; readily quaternized to form stable cationic surfactants and fabric-care actives. - Epoxy curing and crosslinking agent modifier
Employed as a reactive component or accelerator in epoxy formulations and crosslinking systems, providing amine curing sites and tertiary-amine catalytic activity. - Chelating agent and corrosion inhibitor precursor
Used as a building block in synthesis of chelating ligands and corrosion inhibitor molecules for industrial water treatment and metal protection chemistry. - Polyurethane and resin modifiers
Applied in formulations as an intermediate or chain-extender/modifier in specialty polyurethanes, polyureas and resin systems. - Pharmaceutical & agrochemical intermediate (non-final API use)
Serves as an intermediate for fine chemical syntheses and protected-chemistry routes (for industrial intermediates rather than finished pharmaceutical APIs). - Analytical & laboratory reagent
Provided in small packs for R&D, synthetic method development and analytical reference use.
