Description

Cephalin CAS NO 1405-71-6 is a naturally occurring phospholipid, also known as phosphatidylethanolamine, which serves as a fundamental structural and functional component of biological membranes. Its amphiphilic nature makes it an essential material for creating liposomes and lipid bilayers in research and pharmaceutical development. This high-purity biochemical is critical for manufacturers and researchers in the life sciences, pharmaceutical formulation, and diagnostic reagent industries.

Application

• Pharmaceutical Excipient & Drug Delivery: A key component in the formulation of liposomal drug delivery systems for targeted cancer therapies, vaccines, and other advanced therapeutics.
• Biochemical Research & Cell Biology: Used in studies of membrane structure, function, and dynamics, including the reconstitution of membrane proteins and simulation of cellular environments.
• Diagnostic Reagent Production: Employed as a raw material in the manufacturing of reagents for clinical diagnostics, particularly in coagulation studies and lipid metabolism tests.
• Cosmetic & Dermal Formulations: Incorporated into high-end cosmetic products for its emulsifying properties and ability to improve skin barrier function and moisture retention.
• Nutraceuticals & Supplements: Used in advanced nutritional supplements targeting brain health and cognitive function due to its role in neuronal membrane integrity.

Quality Control

Our Cephalin is produced under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for sensitive applications. Each lot undergoes comprehensive analytical testing, including HPLC for phospholipid profile, TLC for purity, and assays for oxidation products. We provide full traceability and Certificates of Analysis (COA) are available for every shipment, detailing all critical quality attributes.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (argon or nitrogen). Under these conditions, the product is typically stable for at least two years. Allow the sealed container to reach room temperature before opening to prevent moisture condensation. Once opened, use promptly and purge the container with inert gas before resealing.
