Used as a lipid-based excipient in drug delivery systems, particularly in liposomal formulations. Its amphiphilic structure, with two oleoyl chains and a reactive succinate moiety, enables stable bilayer formation and conjugation with proteins or other biomolecules for surface modification. This enhances encapsulation, controlled release, and targeted delivery of active pharmaceutical ingredients, especially in cancer and antiviral treatments. Also utilized in transdermal delivery due to its ability to integrate into skin lipid layers, improving permeability of therapeutic agents. Shows low toxicity and good biocompatibility, making it suitable for experimental and preclinical pharmaceutical development. Additionally, serves as a model lipid for studying phospholipid arrangement in artificial cell membranes.
