Chemical Structure
Basic Info
Dodecyltrimethylammonium Chloride (CAS 112-00-5), commonly abbreviated as DTAC, is a high-performance cationic quaternary ammonium surfactant. Featuring a 12-carbon hydrophobic alkyl chain coupled with a hydrophilic trimethylammonium head group, DTAC provides exceptional surface activity, emulsification, dispersibility, and anti-static characteristics across varied pH ranges.
At Zhishang Chem, we manufacture and supply industrial-grade and high-purity laboratory-grade DTAC under strict process controls. The compound demonstrates high chemical stability, excellent solubility in water and polar organic solvents, and strong compatibility with non-ionic additives. Whether applied as a key functional additive in polymer processing, an emulsifying agent in specialty coatings, or a phase transfer catalyst in organic synthesis, our Dodecyltrimethylammonium Chloride satisfies stringent technical standards required by global chemical processors.

To meet international compliance requirements and ensure smooth customs clearance for our buyers worldwide, Zhishang Chem maintains full transparency in quality assurance and global regulatory standards:
ISO 9001:2015 Certification: Our manufacturing facilities operate under certified Quality Management Systems, ensuring batch-to-batch consistency and rigorous raw material sourcing.
REACH Compliance (EU): Registration and technical documentation support are available for clients importing into European markets.
Full Documentation Package: Every commercial shipment is accompanied by a batch-specific Certificate of Analysis (COA), Safety Data Sheet (SDS / MSDS) aligned with GHS standards, and Technical Data Sheet (TDS).
Environmental & Handling Compliance: Detailed guidelines are provided to assist clients with local environmental storage and industrial safety protocols regarding quaternary ammonium compounds.
To ensure that every lot of Dodecyltrimethylammonium Chloride strictly matches your formulation targets, our quality control laboratory executes multi-stage analytical testing before release:
Active Matter Titration (Purity Verification) Using two-phase titration and argentometric titration, we verify active quaternary content to ensure accurate active concentrations (available in powder forms up to ≥98% purity or customized aqueous preparations).
Free Amine & Amine Salt Content Unreacted raw materials are strictly monitored and kept at negligible levels to eliminate odor issues and prevent unwanted side reactions in downstream applications.
Moisture & Residue Analysis Utilizing Karl Fischer titration and loss-on-drying evaluation, we control moisture absorption levels—critical for powder storage stability and formulation precision.
pH & Solution Clarity Aqueous dissolution testing (10% standard solution) confirms complete clarity without suspended particles, ensuring optimal behavior in sensitive emulsions and liquid blends.
