    Product Description

    N,N-Dimethylethanolamine (DMEA), CAS 108-01-0, is a tertiary alkanolamine also named 2-(dimethylamino)ethanol; the EC/EINECS number is 203-542-8.

    Synonyms: 2-(Dimethylamino)ethanol; Dimethylethanolamine; DMEA; Dimethylaminoethanol; N,N-Dimethyl-2-hydroxyethylamine.

    CAS: 108-01-0.

    Molecular formula: C₄H₁₁NO.

    Molecular weight: 89.14.

    EC number: 203-542-8.

    It is a clear, colorless, flammable liquid with an amine odor that is miscible with water, ethanol, ether, acetone and aromatic solvents.

    Typical properties include melting point about -70 °C, boiling point about 134-136 °C, flash point about 40.5 °C (open cup), relative density about 0.886 and refractive index about 1.4294.

    It is widely used as a polyurethane foam catalyst and as an intermediate for ion-exchange resins, pharmaceuticals, dyes and coating solvents.

    It is also used as a neutralizer or co-solvent in waterborne coatings, a curing agent for polyurethane paints, a corrosion-inhibitor building block and a precursor for flocculants in water treatment.

    Confirm assay, water content, color, amine value and related alkanolamine impurities; low-water DMEA is often preferred for polyurethane and resin applications, so purity and water content should match the intended process.

    DMEA is flammable and amine-based. Store in tightly closed containers in a cool, ventilated area below about 30 °C, away from heat, sparks, open flames, strong oxidizers, acids and metal powders, and use chemical-resistant PPE and vapor controls.

    FAQ - Technical & Supply Chain

    • Q:

      What is N,N-Dimethylethanolamine and how is it identified?

      A: N,N-Dimethylethanolamine, commonly called DMEA or dimethylethanolamine, has CAS 108-01-0, molecular formula C₄H₁₁NO and molecular weight 89.14. It is also known as 2-(dimethylamino)ethanol, and is a clear tertiary alkanolamine with both amine and hydroxyl groups.
    • Q:

      What is N,N-Dimethylethanolamine used for?

      A: DMEA is used as a polyurethane catalyst, ion-exchange resin intermediate, coating and ink additive, neutralizer and corrosion-inhibitor building block. It is also used in pharmaceutical, dye and selected solvent formulations.
    • Q:

      Which specifications should be checked before purchasing DMEA?

      A: Confirm assay, water content, color, amine value and related alkanolamine impurities. Low-water DMEA is often preferred for polyurethane and resin applications, so the actual purity and water content should match the intended process.
    • Q:

      Why does water content matter for N,N-Dimethylethanolamine?

      A: Water can affect reactivity in polyurethane systems, change amine activity and introduce side reactions in moisture-sensitive formulations. The product page lists water content at or below 0.1%, but the required limit should be confirmed for each application.
    • Q:

      How should N,N-Dimethylethanolamine be stored and handled?

      A: DMEA is flammable and amine-based. Store it in tightly closed containers in a cool, ventilated area below about 30 °C, away from heat, sparks, open flames, strong oxidizers, acids and metal powders, and use chemical-resistant PPE and vapor controls.
