octyltrimethylammonium bromide

Description:
Octyltrimethylammonium bromide, with the CAS number 2083-68-3, is a quaternary ammonium salt characterized by its surfactant properties. It consists of a long hydrophobic octyl chain and a positively charged trimethylammonium group, making it amphiphilic. This structure allows it to effectively reduce surface tension and stabilize emulsions, making it useful in various applications, including as a surfactant in detergents, emulsifiers in cosmetics, and in the formulation of pharmaceuticals. The bromide ion serves as the counterion, contributing to the compound's solubility in polar solvents. Octyltrimethylammonium bromide is typically a white to off-white solid at room temperature and is soluble in water and organic solvents. It exhibits antimicrobial properties, which can be beneficial in preserving formulations. However, like many quaternary ammonium compounds, it may pose environmental concerns due to its potential toxicity to aquatic life. Proper handling and disposal are essential to mitigate any adverse effects.
