Quality Control

Every batch of 1-Stearoyl-3-Myristoyl-Glycero-2-Phosphocholine is manufactured under strict quality management systems and undergoes comprehensive analytical characterization. We ensure compliance with stringent internal specifications for identity, purity, and acyl chain composition. A detailed Certificate of Analysis (COA) providing HPLC purity, NMR structural confirmation, and critical lipid profile data is supplied with each shipment to guarantee reproducibility and reliability for your most sensitive 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) for long-term stability. This product is hygroscopic (moisture-sensitive). Allow the sealed vial to equilibrate to room temperature before opening to prevent condensation and moisture uptake.
