1,2-Dioleoyl-sn-glycero-3-[(N-(5-amino-1-carboxypentyl)iminodiacetic acid)succinyl] (ammonium salt) is an amphiphilic chelating lipid used in biochemical and biomedical research.

Its iminodiacetic acid (IDA) moiety enables coordination with transition metal ions such as Ni²⁺, Cu²⁺, or Co²⁺, making it ideal for immobilizing His-tagged proteins in purification, affinity chromatography, and surface plasmon resonance studies. The lipid component allows incorporation into liposomes, lipid nanoparticles, or supported lipid bilayers, facilitating protein-membrane interactions and biosensor development.

Additionally, it supports targeted drug delivery systems by enhancing liposome stability and enabling conjugation of biomolecules for cell-specific targeting. Applications include molecular cell biology, fluorescence microscopy for cellular imaging, and gene delivery vectors for DNA/RNA transfection due to its ability to form vesicles and improve cellular uptake.
