Dodecylethyldimethylammonium bromide (CAS 68207-00-1)

Dodecylethyldimethylammonium bromide, a quaternary ammonium compound, functions primarily as a cationic surfactant with a broad range of applications in scientific research. Comprising a nitrogen atom bonded to a dodecyl and an ethyl group, along with two methyl groups, and paired with a bromide counterion, it effectively modifies interfacial properties like surface tension and emulsification. Its surfactant nature allows it to disrupt intermolecular interactions, enhancing its capability to alter the permeability of interfaces. This makes it invaluable in the study of micellar systems, where it is used to investigate the self-assembly of surfactants into micelles in aqueous solutions, shedding light on molecular dynamics at interfaces. Additionally, it serves as a stabilizer in nanoparticle synthesis, preventing aggregation by surrounding each nanoparticle with a positively charged barrier, thus maintaining dispersion stability. This compound is also explored in environmental science research for its interactions with biological membranes, providing insights into the ecological impact of surfactants and their biodegradability. Through these diverse applications, dodecylethyldimethylammonium bromide contributes significantly to advancements in colloidal science, nanoparticle technology, and environmental safety studies.
