Quality Control

Our 1-Stearoyl-2-Linoleoyl-sn-Glycero-3-Phospho-L-Serine (Monosodium Salt) is manufactured under strict quality systems. Each batch is subjected to rigorous analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed chromatographic data are provided and traceable to primary standards. Production adheres to cGMP guidelines for pharmaceutical-grade raw materials.

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) due to its hygroscopic and light-sensitive nature. For long-term storage, desiccate. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
