Quality Control

Our 1-Stearoyl-2-Oleoyl-Sn-Glycero-3-Phosphate(Monosodium Salt) is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including HPLC for purity and fatty acid composition, NMR for structural confirmation, and mass spectrometry. Certificates of Analysis (COA) detailing all specifications are provided to ensure compliance with your research and cGMP-grade application requirements.

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. The material is hygroscopic (moisture-sensitive); allow the sealed vial to equilibrate to room temperature before opening to prevent condensation.
