Description

Laurylpyridiniumiodide CAS NO 3026-66-2 is a quaternary ammonium salt compound, specifically a pyridinium-based cationic surfactant. This chemical is valued for its potent antimicrobial and surfactant properties, making it a key functional ingredient in specialized formulations. It is primarily sought by manufacturers in the pharmaceutical, personal care, and industrial biocides sectors for its ability to modify surface interactions and provide preservative efficacy.

Application

• Pharmaceutical Preservative & Disinfectant: Used as an active ingredient in antiseptic solutions, surgical scrubs, and disinfectant formulations for its bactericidal and fungicidal activity.
• Personal Care Product Preservative: Incorporated into creams, lotions, and other leave-on or rinse-off products to inhibit microbial growth and extend shelf life.
• Textile & Fiber Treatment: Acts as a softening agent, antistatic agent, and antimicrobial finish for synthetic and natural fibers.
• Industrial Biocide: Employed in cooling water systems, fuel additives, and process streams to control bacterial and algal growth.
• Phase Transfer Catalyst (PTC): Facilitates reactions between reactants in immiscible phases in organic synthesis, particularly for alkylation and esterification processes.
• Analytical Chemistry Reagent: Used in ion-pair chromatography and as a precipitating agent for complex anions.
• Emulsion & Dispersion Stabilizer: Serves as a cationic emulsifier in polymerization reactions and in the preparation of stable colloidal dispersions.
• Research & Development: A key intermediate and model compound for studying the properties of cationic surfactants and quaternary ammonium salts in academic and industrial R&D.

Quality Control

Our Laurylpyridiniumiodide is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your quality requirements.

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 after opening to prevent absorption of atmospheric moisture, which can affect product quality and performance.
