Description

Pe(18:0/18:1(9Z)) is a defined phosphatidylethanolamine (PE), a major phospholipid component of biological membranes. This compound matters for researchers and manufacturers requiring a high-purity, structurally-characterized lipid standard or raw material for advanced formulations. It is essential for professionals in lipidomics research, pharmaceutical development, and the production of liposomes and lipid nanoparticles (LNPs) for drug delivery systems.

Application

• Biomedical Research & Lipidomics: Used as a critical analytical standard for the identification and quantification of phosphatidylethanolamine species in mass spectrometry-based lipidomic studies.
• Pharmaceutical Excipient: Serves as a key phospholipid component in the formulation of liposomes and lipid nanoparticles (LNPs) for targeted drug and gene delivery.
• Cell Membrane Studies: Employed in model membrane systems (e.g., vesicles, supported lipid bilayers) to study membrane biophysics, protein-lipid interactions, and permeability.
• Diagnostic Reagent Manufacturing: Incorporated into reagents and kits used for clinical diagnostics and biochemical assays.
• Cosmetic & Nutraceutical Formulations: Used in high-end cosmetic products for its emulsifying and skin-barrier enhancing properties, and in nutraceuticals as a source of structured phospholipids.

Quality Control

Our Pe(18:0/18:1(9Z)) is produced under stringent quality management systems. Each batch undergoes comprehensive analytical characterization using techniques including HPLC, MS, and NMR to confirm identity, purity, and fatty acid composition. Certificates of Analysis (COA) with lot-specific data are provided to ensure traceability and compliance with your research or cGMP-grade requirements.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation. The product is hygroscopic (moisture-sensitive); allow the sealed vial to equilibrate to room temperature before opening to prevent condensation.
