Description

L-A-Phosphatidic Acid Dipalmitoyl*Sodium is a high-purity, synthetic phospholipid salt, specifically the sodium salt of 1,2-dipalmitoyl-sn-glycero-3-phosphate. This compound serves as a critical building block and model lipid for advanced research and formulation development in life sciences. It is essential for scientists and manufacturers in the pharmaceutical, biotechnology, and nutraceutical industries who require well-defined lipid components for creating liposomes, studying membrane biophysics, and developing lipid-based drug delivery systems.

Application

• Liposome & Lipid Nanoparticle (LNP) Formulation: A key anionic phospholipid component for constructing stable, charged liposomal bilayers used in drug and gene delivery.
• Biochemical & Membrane Research: Used as a standard or substrate in enzymatic assays (e.g., phospholipase studies) and for modeling cell membrane properties and signaling pathways.
• Pharmaceutical Excipient: Employed in the development of lipid-based drug delivery systems to enhance solubility, stability, and bioavailability of active pharmaceutical ingredients (APIs).
• Cosmetic & Dermal Formulations: Acts as a biomimetic emulsifier and skin-conditioning agent in high-end cosmetic products designed for improved skin barrier function.
• Nutraceutical Encapsulation: Used to create specialized lipid vesicles for the targeted delivery of sensitive nutrients and supplements.
• Diagnostic Reagent Production: Serves as a raw material in the manufacture of diagnostic kits and reagents that involve lipid membranes or specific lipid-protein interactions.
