    Product Description

    Dodecyltrimethylammonium Chloride (DTAC) CAS 112-00-5 is a cationic quaternary ammonium surfactant, with EC 203-927-0 and molecular formula C15H34ClN.

    Synonyms: Lauryltrimethylammonium Chloride; n-Dodecyltrimethylammonium Chloride; DTAC.

    CAS: 112-00-5.

    Molecular formula: C15H34ClN.

    It has a molecular weight of about 263.89 g/mol.

    It is supplied as an aqueous solution or as a high-purity solid or powder.

    Commercial supply is commonly provided as a 30% or 50% aqueous solution for industrial formulation use.

    It is positioned as a cationic surfactant for industrial formulations requiring surface activity, emulsification, and antistatic or conditioning performance.

    It is used in textile antistatic and softening auxiliaries, coatings, and emulsification.

    It is used in phase-transfer catalysis and specialty formulations.

    It contributes to dispersion, wetting, conditioning, and surface modification.

    It is compatible with formulation systems where cationic functionality is required, and should not be mixed with incompatible anionic materials.

    Confirm the required grade, active content, pH, appearance, solubility, and related specifications for the chosen grade.

    Store in tightly closed containers in a cool, dry, well-ventilated area, away from direct sunlight and strong oxidizing agents.

    Avoid mixing with incompatible anionic materials, and use appropriate protective equipment when handling the liquid or solid.

    Confirm packaging suitable for the liquid or solid form and order quantity, and follow the current SDS.

    Confirm grade, packaging, and specification as required.

    FAQ - Technical & Supply Chain

    • Q:

      What is Dodecyltrimethylammonium Chloride CAS 112-00-5?

      A: Dodecyltrimethylammonium chloride, commonly abbreviated DTAC, is a cationic quaternary ammonium surfactant with the molecular formula C15H34ClN. It contains a C12 dodecyl chain attached to a trimethylammonium head group and is commonly supplied as an aqueous solution or as a high-purity solid.
    • Q:

      Why is the correct CAS number for DTAC 112-00-5?

      A: The chemical name Dodecyltrimethylammonium Chloride corresponds to CAS 112-00-5 in authoritative supplier and regulatory listings. CAS 7173-62-8 identifies a different amine product, N-oleyl-1,3-propanediamine, so the two identifiers must not be used interchangeably.
    • Q:

      What concentrations and forms of DTAC are commonly supplied?

      A: DTAC is often available as a 30% or 50% aqueous solution for industrial formulation use, and can also be supplied as a higher-purity solid or powder. The selected form should match the active content, handling requirements, and intended formulation system.
    • Q:

      What are the main applications of Dodecyltrimethylammonium Chloride?

      A: It is used as a cationic surfactant in textile antistatic and softening auxiliaries, coatings, emulsification, phase-transfer catalysis, and specialty formulations. Its surface activity also supports wetting, conditioning, and quaternary ammonium intermediate applications.
    • Q:

      How should DTAC be stored and handled?

      A: Keep DTAC in tightly closed containers in a cool, dry, well-ventilated area away from direct sunlight and strong oxidizing agents. Avoid mixing with incompatible anionic materials, and use appropriate protective equipment when handling the liquid or solid.
