Description

1-Hexadecylpyridine n-Oxide is a cationic surfactant and a member of the pyridine N-oxide family, characterized by a long hydrophobic alkyl chain. This amphiphilic structure makes it a valuable chemical intermediate and functional additive, particularly effective in modifying surface properties and facilitating phase transfer. It is primarily sought by manufacturers in the specialty chemical, pharmaceutical, and material science sectors for applications requiring emulsification, dispersion, or antimicrobial activity. Its utility extends to research and development as a model compound for studying surfactant behavior and interfacial phenomena.

Application

• Surfactant & Emulsifier: Used in the formulation of industrial cleaners, degreasers, and specialty detergents where its cationic nature provides effective surface wetting and soil removal.
• Phase Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases (e.g., aqueous and organic) in synthetic organic chemistry and pharmaceutical manufacturing.
• Antimicrobial Agent: Incorporated into disinfectant formulations and preservative systems for its biocidal properties against a broad spectrum of microorganisms.
• Material Science Additive: Serves as a modifier or compatibilizer in polymer composites and coatings to improve dispersion of fillers and enhance material properties.
• Analytical Chemistry Reagent: Employed in extraction processes and as a component in sensor technologies due to its selective binding capabilities.
• Research & Development: Acts as a standard or building block in academic and industrial R&D for synthesizing more complex pyridinium compounds or studying micelle formation.

Quality Control

Our 1-Hexadecylpyridine n-Oxide is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with key parameters such as assay, moisture content, and residual solvents. While produced to meet general industrial and research-grade standards, specifications can be aligned with specific customer requirements. Certificates 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 (typically 15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to minimize exposure to atmospheric humidity. Keep away from strong oxidizing agents.
