Description

Dodecyltrimethylammonium Bromide CAS NO 1119-94-4 is a high-purity quaternary ammonium salt (quat) surfactant, valued for its potent cationic properties and excellent surface activity. This compound is essential for applications requiring strong emulsification, disinfection, and phase-transfer catalysis. It is a critical raw material for manufacturers in the biocidal, personal care, textile, and polymer industries seeking reliable, high-performance ingredients.

Application

• Biocide & Disinfectant Formulations: A key active ingredient in algaecides, fungicides, and sanitizers for industrial water treatment, agriculture, and surface cleaning.
• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, crucial in organic synthesis for pharmaceuticals and specialty chemicals.
• Surfactant & Emulsifier: Used in hair conditioners, fabric softeners, and other personal care products for its antistatic and softening effects.
• Textile & Leather Processing: Acts as a softening agent, dyeing assistant, and antistatic agent for fibers and leathers.
• Analytical Chemistry: Serves as an ion-pairing agent in chromatography and a modifier in capillary electrophoresis.
• Nanomaterial Synthesis: Functions as a structure-directing agent or stabilizer in the preparation of mesoporous silica and other nanoparticles.
• Oilfield Chemicals: Employed as a corrosion inhibitor and bactericide in drilling and production fluids.
• Paper & Pulp Industry: Used as a retention aid, drainage aid, and biocide in papermaking processes.

Quality Control

Our Dodecyltrimethylammonium Bromide is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets high-purity specifications for critical parameters such as assay, moisture content, and residual solvents. A comprehensive Certificate of Analysis (COA) documenting these results is provided with each shipment to guarantee traceability and compliance with your quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
