Description

Phosphatidylethanolamine CAS NO 90989-93-8 is a major phospholipid component of biological membranes, playing a critical structural and functional role in cellular processes. Its unique amphiphilic nature makes it an essential material for creating liposomes, lipid bilayers, and other biomimetic systems. This high-purity phospholipid is vital for researchers and manufacturers in the pharmaceutical, nutraceutical, and advanced material science industries.

Application

• Liposome & Drug Delivery System Formulation: A key structural lipid for creating stable, biocompatible liposomal carriers for targeted drug and gene delivery.
• Biomimetic Membrane Research: Used to construct model cell membranes (e.g., supported lipid bilayers) for studying membrane proteins, permeability, and cellular interactions.
• Cell Culture & Media Supplement: Employed as a component in serum-free media and supplements to support the growth of specific cell lines.
• Pharmaceutical Excipient: Acts as an emulsifier, solubilizer, and penetration enhancer in topical, injectable, and oral formulations.
• Nutraceutical & Cosmetic Ingredient: Incorporated into supplements for cognitive health and cosmetic products for its skin-barrier repair and moisturizing properties.
• Biochemical Research & Diagnostics: Serves as a substrate for enzymes like phospholipase D and is used in assays to study lipid metabolism and signaling pathways.

Quality Control

Our Phosphatidylethanolamine is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and lipid profile, TLC for identification, and tests for residual solvents and heavy metals. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your research or GMP-grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation and hydrolysis. For long-term stability, the product should be kept desiccated. Allow the sealed vial to reach room temperature before opening to prevent condensation and moisture uptake.
