1,2-Distearoyl-sn-glycero-3-phosphoethanolamine-N-[succinyl-(polyethylene glycol)] ammonium salt is a PEGylated phospholipid designed for enhancing membrane stability, colloidal dispersion, and surface modification in lipid-based systems. The distearoyl chains provide strong hydrophobic anchoring within bilayers, while the succinylated polyethylene glycol moiety extends into the aqueous phase, imparting steric stabilization and resistance to aggregation. This amphiphilic structure is widely utilized in the preparation of liposomes and nanocarriers where long-circulating or stealth properties are required for physicochemical investigations. It also enables systematic studies on PEG-lipid interactions, membrane hydration, and polymer–lipid coupling effects, making it a cornerstone compound in the advancement of lipid assembly and nanostructure engineering research.
