Ethylhexadecyldimethylammonium bromide (CAS 124-03-8)

Ethylhexadecyldimethylammonium bromide (EHDMAB) is a quaternary ammonium compound predominantly used in the field of biochemistry for its surfactant properties. The molecule consists of a long ethylhexadecyl hydrophobic tail and a positively charged headgroup, making it ideal for studies involving membrane interactions. EHDMAB is particularly effective in solubilizing cell membranes, a function that is vital for extracting and purifying membrane-associated proteins. This surfactant′s ability to disrupt lipid bilayers is also leveraged in the encapsulation of enzymes and other biomolecules into vesicles, aiding in the study of their properties in a controlled, membrane-like environment. Additionally, EHDMAB finds utility in the synthesis of micelles and liposomes, where it acts to stabilize these structures and modify their surface characteristics for targeted research applications. The compound′s role in facilitating the transfer of genetic material across cell membranes without the use of viral vectors is another critical area of research, contributing to the development of non-viral gene delivery methods.
