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.

• 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.

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.
