Description

1-Tetradecylpyridinium Bromide is a high-purity quaternary ammonium salt (quat) surfactant and cationic disinfectant. This compound is valued for its potent antimicrobial and surface-active properties, making it a critical component in formulations requiring biocidal efficacy and charge modification. It is primarily sought by manufacturers in the disinfection, personal care, textile processing, and water treatment industries for its reliable performance and stability.

Application

• Disinfectant & Biocide Formulations: A key active ingredient in industrial, institutional, and agricultural disinfectants, sanitizers, and algicides.
• Personal Care & Cosmetics: Used as a preservative and conditioning agent in hair care products and skincare formulations.
• Textile & Fiber Treatment: Functions as a softener, antistatic agent, and dyeing auxiliary for synthetic and natural fibers.
• Water Treatment: Employed as a biocide in cooling towers, pulp/paper mills, and oilfield water systems to control microbial growth.
• Phase Transfer Catalyst: Facilitates reactions between reagents in immiscible solvents in organic synthesis.
• Analytical Chemistry: Used in ion-pair chromatography and as a reagent for precipitating anionic species.
• Surface Modification: Imparts a positive charge to surfaces like silica, clays, and polymers for specialized material applications.
• Research & Development: Serves as a standard or intermediate in chemical, pharmaceutical, and material science research.
