N,N,N-Trimethyl-2,3-bis(stearoyloxy)propan-1-aminium iodide (DSTAP iodide) is a cationic lipid with two saturated C18 stearic acid chains and a permanently charged trimethylammonium headgroup. It forms stable, rigid bilayers and is often used in liposome formulations, nucleic-acid delivery systems, and model membrane research, particularly where thermal or structural stability is important.
