Description

Hexadecyl Trimethyl Ammonium Iodide is a high-purity quaternary ammonium salt (quat) valued for its potent cationic surfactant and antimicrobial properties. This compound is essential for applications requiring a stable, long-chain alkylammonium cation paired with an iodide counterion. It is primarily sought by manufacturers and researchers in the pharmaceutical, biotechnology, and specialty chemical sectors for its role in synthesis, phase-transfer catalysis, and as a biocide or disinfectant precursor.

Application

• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, particularly in organic synthesis and polymer manufacturing.
• Antimicrobial Agent: Serves as an active ingredient or intermediate in the formulation of disinfectants, sanitizers, and algicides.
• Pharmaceutical Intermediate: Used in the synthesis of other quaternary ammonium compounds with specific pharmacological activities.
• Biotechnology Reagent: Employed in nucleic acid purification processes and as a component in cell lysis buffers.
• Surfactant & Emulsifier: Acts as a cationic surfactant in specialty emulsions, fabric softeners, and hair conditioners.
• Analytical Chemistry: Utilized as an ion-pairing agent in chromatographic techniques like HPLC.
• Material Science: Used in the surface modification of nanomaterials and as a template in mesoporous silica synthesis.
• Research & Development: A key reagent for academic and industrial research in organic chemistry and colloid science.
