Description

1-n-Hexadecyl-4-Methylpyridinium Chloride Hydrate is a quaternary ammonium salt (quat) characterized by a long hydrophobic alkyl chain. This compound is valued for its potent cationic surfactant and antimicrobial properties, making it a versatile functional ingredient. It is primarily used in the formulation of disinfectants, sanitizers, and as a phase-transfer catalyst in organic synthesis. Industries such as pharmaceuticals, agrochemicals, and specialty chemicals rely on its consistent quality and performance.

Application

• Disinfectant & Sanitizer Formulations: Acts as a key active ingredient in industrial, institutional, and agricultural biocides due to its broad-spectrum antimicrobial efficacy.
• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, particularly useful in alkylation, esterification, and polymerization processes.
• Surfactant & Emulsifier: Serves as a cationic surfactant in specialty cleaning products, fabric softeners, and emulsion stabilization.
• Pharmaceutical Intermediates: Used in the synthesis of more complex quaternary ammonium compounds with specific biological activities.
• Material Science: Employed in the surface modification of materials, including clay treatment and as a component in conductive polymers.
• Agrochemical Additives: Enhances the efficacy of pesticides and herbicides by improving adhesion and penetration on plant surfaces.

Quality Control

Our 1-n-Hexadecyl-4-Methylpyridinium Chloride Hydrate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting purity, water content, and residual solvents are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
