Description

n-(3-(Hexadecyloxy)-2-Methoxypropyl)-3-(Hydroxymethyl)Pyridinium is a specialized cationic surfactant and quaternary ammonium compound with a unique pyridinium head group and a long-chain alkoxy tail. This molecular structure provides excellent surface activity, making it a valuable intermediate for the synthesis of advanced materials and functional chemicals. It is primarily utilized in the pharmaceutical, agrochemical, and specialty chemical industries for applications requiring cationic modification, antimicrobial properties, or phase-transfer catalysis.

Application

• Pharmaceutical Intermediate: Used in the synthesis of novel drug candidates, particularly those requiring cationic or amphiphilic properties for enhanced bioavailability or targeted delivery.
• Agrochemical Formulations: Acts as an emulsifier, dispersant, or active ingredient component in pesticides and herbicides to improve stability and efficacy.
• Antimicrobial Agent: Serves as a precursor or active component in disinfectants, sanitizers, and preservatives due to its quaternary ammonium structure.
• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases in organic synthesis, improving yield and reaction rate.
• Surface Modification Agent: Used to impart cationic charge or modify surface properties of polymers, textiles, and nanoparticles.
• Research & Development: A key building block in academic and industrial R&D for exploring new surfactants, ionic liquids, and functional materials.

Quality Control

Our n-(3-(Hexadecyloxy)-2-Methoxypropyl)-3-(Hydroxymethyl)Pyridinium is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and moisture content, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
