N-(2,3-bis(stearoyloxy)propyl)-N,N-dimethylprop-2-yn-1-aminium bromide is a cationic amphiphilic lipid featuring two saturated C18 (stearoyl) tails for high membrane order and thermal stability, A dimethyl-propargylammonium headgroup for permanent positive charge and click-reactive alkyne functionality and a bromide counterion. It forms rigid, positively charged bilayers and is particularly useful for functional liposome design, click-modified lipid systems, and advanced delivery formulations where controlled conjugation or membrane labeling is desired.
