Description

Di-(8-n-Butylstearoyl)Phosphatidylcholine is a synthetic, chemically defined phospholipid derivative designed for advanced research and high-precision formulation. This compound matters for its role as a critical functional excipient and model membrane component, offering superior batch-to-batch consistency compared to natural extracts. It is essential for pharmaceutical scientists, cosmetic formulators, and biophysical researchers developing liposomal drug delivery systems, advanced dermal applications, and studying membrane biophysics.

Application

• Liposomal Drug Delivery Systems: As a key structural phospholipid for creating stable, targeted liposomes for encapsulating active pharmaceutical ingredients (APIs).
• Advanced Cosmetic Formulations: Used in high-end skincare and anti-aging products for its emulsifying and skin-barrier enhancing properties.
• Biophysical & Membrane Research: Serves as a defined component in model membrane studies (e.g., vesicles, bilayers) to investigate lipid-protein interactions and membrane dynamics.
• Diagnostic Reagents: Employed in the formulation of lipid-based reagents for clinical diagnostics and analytical assays.
• Biomimetic Coatings: Utilized to create biocompatible surfaces and coatings for medical devices and implants.
• Nutraceutical Encapsulation: For the microencapsulation of sensitive vitamins and nutrients to improve stability and bioavailability.

Quality Control

Our Di-(8-n-Butylstearoyl)Phosphatidylcholine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (NMR, IR), to ensure it meets stringent specifications for research and cGMP-guided applications. Certificates of Analysis (COA) detailing all critical quality attributes are available upon request.

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) to prevent oxidation and hydrolysis. For long-term storage, desiccate to protect against moisture. Allow the sealed container to reach room temperature before opening to minimize condensation.
