Dimethyldioctadecylammonium bromide  (Synonyms: Dioctadecyldimethylammonium bromide; DODAB)

Dimethyldioctadecylammonium bromide is a synthetic cationic lipid commonly used in gene delivery and vaccine development. Also known as DODAB or DDAB, it consists of a positively charged ammonium head group and two long hydrophobic tails. These properties make it useful for forming liposomes and other lipid-based nanoparticles that can efficiently deliver genetic material into cells. In addition to its applications in biotechnology, DDAB is also used in surfactants, emulsifiers and fabric softeners. However, due to its potential toxicity and irritation, extreme care should be taken when handling DDAB.

Dimethyldioctadecylammonium (bromide) is a biochemical reagent that can be used as a biological material or organic compound for life science related research.
