Description

Tetradecyltrimethylammonium Hydrogen Sulfate is a quaternary ammonium salt surfactant with a long alkyl chain, valued for its potent cationic properties and phase-transfer catalytic capabilities. This compound is essential for facilitating reactions in heterogeneous systems and serves as a critical component in the formulation of specialized biocides and fabric softeners. It is primarily sought by manufacturers in the chemical synthesis, personal care, textile treatment, and industrial cleaning sectors for its reliable performance and structural versatility.

Application

• Phase-Transfer Catalyst (PTC): Enables reactions between reagents in immiscible phases, particularly in alkylation, esterification, and polymerization processes.
• Biocide & Disinfectant Formulations: Acts as an active ingredient in industrial and institutional disinfectants due to its antimicrobial efficacy against bacteria and fungi.
• Textile Auxiliary Agent: Used as a softener and antistatic agent for synthetic fibers, providing a smooth hand feel and reducing static cling.
• Emulsifier & Surfactant: Stabilizes emulsions in specialty cleaning products, coatings, and agrochemical formulations.
• Analytical Chemistry Reagent: Employed in ion-pair chromatography and as a modifier in capillary electrophoresis for separating ionic compounds.
• Corrosion Inhibitor: Provides protective films in acidizing solutions and cooling water systems for industrial equipment.
• Personal Care Products: Functions as a conditioning agent in hair care products, offering detangling and anti-frizz properties.
• Research & Development: Serves as a key intermediate or standard in organic synthesis and material science research.

Quality Control

Our Tetradecyltrimethylammonium Hydrogen Sulfate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications for industrial and research applications. Certificates of Analysis (COA) documenting purity, physical characteristics, and test results are provided with every shipment and are available upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
