Widely used in pharmaceutical and biotechnology industries as a key component in liposome formulations. Its structure supports the formation of stable lipid bilayers, making it ideal for drug delivery systems, especially in targeted cancer therapies and mRNA-based vaccines. Commonly employed in transfection reagents to facilitate cellular uptake of nucleic acids. Also utilized in research settings to study membrane dynamics and lipid-protein interactions. Its ammonium salt form enhances solubility and stability in aqueous environments, improving performance in both in vitro and in vivo applications.
