Quality Control

Our Dl-A-Phosphatidylethanolamine is produced and tested under strict quality management systems. Each batch undergoes comprehensive analysis to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters such as assay (HPLC), fatty acid profile, and oxidation status. Our quality commitment supports applications requiring high-purity phospholipids for research and GMP-grade formulation development.

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 storage, desiccate. Allow the sealed container to reach room temperature before opening to prevent condensation and moisture ingress.
