Quality Control

Our L-α-Phosphatidylinositol (Liver, Bovine) (Sodium Salt) is manufactured under strict quality management systems. Each batch is characterized using advanced analytical techniques including HPLC, TLC, and NMR to confirm identity, purity, and fatty acid profile. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, impurities, and solvent residues. The production process is designed to meet the exacting standards required for research and pharmaceutical auxiliary applications.

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 minimize oxidation and hydrolysis. For long-term storage, desiccate at -20°C. The material is hygroscopic and light-sensitive; allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
