Description

Triethyloctadecylammonium 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. Its structure provides excellent surface activity and antimicrobial efficacy, making it a critical component in formulations requiring stability and performance. This compound is essential for manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking reliable, high-quality raw materials for synthesis and product development.

Application

• Phase-Transfer Catalyst (PTC): Widely used in organic synthesis to facilitate reactions between reagents in immiscible phases, particularly in alkylation, esterification, and polymerization processes.
• Antimicrobial Agent: Serves as an active ingredient in disinfectants, sanitizers, and preservative formulations for industrial and institutional cleaning products.
• Surfactant & Emulsifier: Functions as a cationic surfactant in the production of fabric softeners, hair conditioners, and other personal care products requiring substantive conditioning.
• Chemical Intermediate: Used in the synthesis of other quaternary ammonium compounds and specialty chemicals for various industrial applications.
• Agrochemical Formulations: Employed as an additive in pesticides and herbicides to enhance adhesion, penetration, and overall efficacy on plant surfaces.
• Corrosion Inhibitor: Applied in industrial water treatment and oilfield chemicals to protect metal surfaces from corrosion.
