Quality Control

Our L-A-Phosphatidylinositol is produced and tested under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and fatty acid profile analysis, TLC for identity and impurity screening, and specific tests for residual solvents and heavy metals. We provide full traceability and Certificates of Analysis (COA) are available for every shipment, ensuring compliance with research and cGMP-grade material requirements where applicable.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store unopened vials at -20°C or below under an inert atmosphere (e.g., argon or nitrogen). This product is hygroscopic (moisture-sensitive) and easily oxidized. Once opened, use immediately and do not expose to air for prolonged periods. Allow the sealed container to reach room temperature before opening to prevent condensation.
