HexadecylPyridinium chloride

Description:
Hexadecylpyridinium chloride, with the CAS number 123-03-5, is a quaternary ammonium compound characterized by its long hydrophobic alkyl chain (hexadecyl) and a positively charged pyridinium ring. This compound typically appears as a white to off-white solid or powder and is soluble in water and organic solvents, making it versatile in various applications. It exhibits surfactant properties, allowing it to reduce surface tension and stabilize emulsions. Hexadecylpyridinium chloride is often used as a cationic surfactant in personal care products, pharmaceuticals, and as a disinfectant due to its antimicrobial properties. Its structure contributes to its ability to interact with biological membranes, which can enhance its effectiveness in antimicrobial applications. However, caution is advised in handling this compound, as it can be toxic to aquatic life and may cause irritation upon contact with skin or eyes. Proper safety measures should be observed when working with this substance in laboratory or industrial settings.
