DTAC Procurement Specs: CAS 112-00-5 Free Amine & Purity Data
Defining DTAC Chemical Identity: CAS 112-00-5 and Molecular Weight
Dodecyl Trimethyl Ammonium Chloride, universally identified by CAS 112-00-5, functions as a critical quaternary ammonium compound in industrial formulation. The molecular formula C12H25(CH3)3NCl dictates a molecular weight of 263.9 g/mol, establishing the stoichiometric baseline for all active content calculations. This cationic surfactant structure comprises a hydrophobic dodecyl chain and a hydrophilic trimethylammonium head group, driving its surface activity and solubility profile in polar solvents like water and ethanol. At NINGBO INNO PHARMCHEM CO.,LTD., we prioritize precise molecular characterization to ensure batch-to-batch reproducibility essential for downstream synthesis.
The chemical identity extends beyond simple nomenclature; it defines the material's role as a phase transfer catalyst and emulsifier. The chloride counter-ion contributes to the compound's ionic strength in solution, influencing conductivity and interaction with anionic species. Procurement teams must verify the EINECS number 203-927-0 alongside the CAS registry to confirm regulatory alignment in non-EU contexts, focusing strictly on chemical composition rather than external compliance certifications. The physical state typically presents as a colorless liquid to white crystalline powder, dependent on concentration and temperature, requiring clear specification in purchase orders to avoid logistical discrepancies regarding viscosity and handling.
DTAC Procurement Specs: Free Amine Limits and Active Content Analysis
Technical procurement of Dodecyl Trimethyl Ammonium Chloride requires rigorous validation of active content and impurity profiles, specifically free amine levels. High free amine content can induce odor issues, reduce stability in acidic formulations, and alter the cationic charge density required for effective substrate binding. Our standard specifications mandate a free amine limit of 1.5% maximum, ensuring the quaternization reaction proceeds to near-completion. This parameter is critical for applications requiring low odor profiles, such as cosmetics and personal care conditioners, where residual tertiary amines are unacceptable.
Active content variability directly impacts formulation economics and performance consistency. Industrial grades typically range between 28-32% or 48-52% active matter in aqueous solution. Purchasing based on active content rather than gross weight prevents cost inefficiencies associated with excessive water content. The following table outlines the critical quality parameters required for technical acceptance:
| Parameter | Standard Grade Specification | High Purity Grade Specification |
|---|---|---|
| Appearance | Colorless to pale yellow liquid | Colorless to pale yellow liquid |
| Active Content (%) | 28-32 | 48-52 |
| Free Amine (%) | 1.5 max | 1.5 max |
| pH (10% Aqueous Solution) | 5.0-9.0 | 5.0-9.0 |
| Color (APHA) | 150 max | 150 max |
Verification of these specs requires GC-MS analysis and titration methods documented in the Certificate of Analysis (COA). Procurement contracts should specify tolerance limits for active content to avoid disputes upon delivery.

Consistency in active matter ensures that formulation ratios remain stable across production runs, minimizing the need for recalibration in automated dosing systems.
Technical Quality Indices: pH Stability, Color APHA, and Heat Resistance
Thermal and chemical stability are paramount for DTAC performance in harsh industrial environments. The compound maintains structural integrity below 100°C, making it suitable for processes involving moderate heat but requiring caution in high-temperature sterilization or exothermic reactions. Decomposition above this threshold can release volatile amines and degrade surfactant efficacy. The pH stability range of 5.0-9.0 in a 10% water solution indicates robustness across neutral to slightly alkaline conditions, though compatibility with strong acids or bases must be tested prior to bulk mixing to prevent hydrolysis of the quaternary bond.
Color stability, measured in APHA units, serves as a key indicator of oxidation and impurity levels. A maximum limit of 150 APHA ensures the material remains suitable for light-colored formulations without requiring extensive bleaching or masking agents. Oxidation during storage can darken the liquid, signaling potential degradation of the alkyl chain. Light resistance and pressure resistance further contribute to the material's utility in sealed systems where exposure to UV or mechanical stress occurs. Procurement specifications should mandate APHA testing on every batch to monitor supply chain storage conditions, as exposure to direct sunlight or excessive heat during transit can compromise color standards before the material reaches the manufacturing floor.
Industrial Application Compliance for Drilling, Cosmetics, and Synthetic Fiber
Application-specific compliance dictates the required purity grade and packaging configuration. In the oilfield sector, DTAC functions as an emulsifier in drilling fluids, requiring high-temperature resistance to maintain viscosity and stability under downhole conditions. The material's ability to act as a protein aggregation agent in penicillin fermentation highlights its biocompatibility at specific concentrations, though biocide applications require strict adherence to dosage regulations to prevent environmental toxicity. For synthetic fiber production, the compound serves as an antistatic agent, where residual free amine must be minimized to prevent fiber discoloration or degradation during spinning.
In cosmetic formulations, such as conditioner emulsifiers, the focus shifts to sensory properties and safety data. The material's softness and permeability enhancements are valuable, but the COA must confirm low heavy metal content and microbial limits. Architectural waterproof coatings utilize DTAC for its emulsification properties in latex systems, requiring compatibility with anionic stabilizers to prevent coagulation. For engineers evaluating alternative sources, our technical team provides data on Dodecyl Trimethyl Ammonium Chloride drop-in replacement for Tci I0453 Dtac to ensure formulation parity without requalification delays. Each application sector demands a tailored specification sheet aligning with the specific mechanical and chemical stresses of the end-use environment.
Supplier Verification for Surfactant Compatibility and Batch Consistency
Verifying supplier capability involves assessing batch consistency and compatibility with existing surfactant systems. DTAC exhibits good compatibility with cationic and nonionic surfactants but may precipitate when mixed with anionic species due to charge neutralization. Procurement audits should include requests for historical COA data to analyze variance in active content and pH over time. Consistent batch performance reduces the risk of production line stoppages caused by viscosity shifts or phase separation in final products. NINGBO INNO PHARMCHEM CO.,LTD. maintains rigorous quality control protocols to ensure that industrial purity standards are met consistently across large-volume orders.
Logistical compliance is equally critical, given the hazard classification of Corrosive and Toxic, Class 8+6.1, UN2922. Suppliers must provide accurate safety data sheets and ensure packaging integrity for 200L drums or 1000L IBCs to prevent leakage during transport. Storage requirements dictate a shady, dry environment to maintain stability over the shelf life, typically up to 10 months under optimal conditions. Verification processes should include inspection of packaging labels for UN codes and hazard symbols to ensure regulatory compliance during inbound logistics. Establishing a validated supplier relationship ensures access to consistent technical support and reliable supply chains for critical chemical inputs.
