CAS 1120-02-1: Octadecyltrimethylammonium bromide

Description: Octadecyltrimethylammonium bromide (OTAB) is a quaternary ammonium salt characterized by its long hydrophobic alkyl chain and a positively charged nitrogen atom. It typically appears as a white to off-white powder and is soluble in polar organic solvents, while being insoluble in water due to its hydrophobic nature. OTAB is commonly used as a surfactant, emulsifier, and phase transfer catalyst in various chemical processes. Its amphiphilic properties allow it to reduce surface tension and stabilize emulsions, making it valuable in formulations such as cosmetics, pharmaceuticals, and industrial applications. Additionally, OTAB can interact with anionic species, which can lead to the formation of complexes or aggregates. It is important to handle this compound with care, as quaternary ammonium compounds can exhibit antimicrobial properties and may pose environmental concerns if released in significant quantities. Overall, OTAB's unique structure and properties make it a versatile compound in both research and industrial settings.
