Description

Eicosyltriethylammonium Bromide is a high-purity quaternary ammonium salt (quat) with a long alkyl chain, valued for its potent cationic surfactant and phase-transfer catalyst properties. This compound is essential for facilitating reactions in non-polar media and is a key ingredient in the formulation of specialized biocides and fabric softeners. It serves critical roles in the chemical synthesis, textile treatment, and industrial biocide sectors, where its structure provides unique solubility and efficacy advantages.

Application

• Phase-Transfer Catalyst (PTC): Enables reactions between reagents in immiscible liquid phases, crucial for alkylation, esterification, and other organic synthesis processes.
• Biocide & Disinfectant Formulations: Used as an active ingredient or co-formulant in industrial and institutional disinfectants, algicides, and sanitizers due to its antimicrobial properties.
• Textile & Fabric Softener Agent: Imparts a soft, antistatic finish to fibers and fabrics as a cationic softening agent.
• Emulsifier & Surfactant: Acts as a cationic emulsifier in the production of polymers, coatings, and specialty emulsions.
• Analytical Chemistry Reagent: Employed in ion-pair chromatography and as a standard for analytical method development.
• Corrosion Inhibitor: Functions as an additive in industrial water treatment and cooling systems to protect metal surfaces.
