Description

L-A-Phosphatidylcholine Diheptadecanoyl Synthetic is a high-purity, synthetically produced phospholipid where both fatty acid chains are heptadecanoic acid, offering exceptional batch-to-batch consistency. This compound is critical for research and development where defined molecular structure and purity are paramount, eliminating the variability associated with natural sources. It is an essential material for pharmaceutical formulation scientists, advanced lipidomics researchers, and developers of high-performance liposomal drug delivery systems and diagnostic reagents.

Application

• Liposomal Drug Delivery Systems: As a primary component for creating stable, uniform, and reproducible liposome formulations for targeted therapeutic delivery.
• Biomembrane & Biophysical Research: Used as a standard or model membrane lipid in studies of membrane fluidity, protein-lipid interactions, and bilayer dynamics due to its synthetic purity.
• Pharmaceutical Excipient: Acts as an emulsifying agent, solubilizer, and penetration enhancer in various injectable and topical drug formulations.
• Diagnostic Reagents: Employed in the manufacture of calibrators, controls, and reagents for clinical diagnostic assays, particularly in enzymology and immunology.
• Reference Standard: Serves as a high-purity analytical standard in lipidomics and quality control laboratories for method development and validation.
• Nutraceutical & Cosmeceutical R&D: Investigated for use in advanced nutritional supplements and cosmetic products requiring specific, stable phospholipid profiles.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) for long-term stability. This product is hygroscopic (moisture-sensitive) and easily oxidized; allow the sealed container to reach room temperature before opening to prevent condensation. For short-term use, store desiccated at 2-8°C.
