Quality Control

Our D-Erythro-Sphingosyl Phosphoinositol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment, supporting compliance with research and development standards.

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 prevent oxidation and hydrolysis. The product is hygroscopic (moisture-sensitive) and must be handled in a dry environment. Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture condensation.
