Description

1-Myristoyl-2-Stearoylphosphatidylcholine is a synthetic, high-purity phospholipid with a defined fatty acid composition, offering superior consistency and performance over natural lecithin extracts. This compound is critical for creating stable, reproducible lipid-based delivery systems and biomimetic membranes. It is an essential material for pharmaceutical, biotechnology, and advanced cosmetic research and manufacturing, where precise molecular structure dictates functional outcomes.

Application

• Liposome & Nanoparticle Formulation: A key structural phospholipid for constructing drug delivery vesicles (e.g., liposomes, solid lipid nanoparticles) for targeted and sustained release applications.
• Biomembrane & Model System Research: Used to create defined lipid bilayers for studying membrane protein interactions, permeability, and cell signaling mechanisms.
• Pharmaceutical Excipient: Serves as an emulsifier, solubilizer, and penetration enhancer in injectable and topical formulations.
• Diagnostic Reagent Component: Employed in the production of reagents for clinical diagnostics and analytical assays requiring specific lipid environments.
• Cosmetic Actives Carrier: Enhances the skin delivery and stability of active ingredients in high-performance skincare products.
• Cell Culture & Cryopreservation: Used as a supplement in media formulations and cryoprotectants to maintain cell membrane integrity.
