Quality Control

Every batch of C15 Galactosylceramide (D18:1/15:0) is manufactured under controlled conditions and undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our quality system is designed to meet the stringent requirements of research and development. A comprehensive Certificate of Analysis (COA) detailing purity (by HPLC), identity confirmation (by NMR/MS), and impurity profiles is provided with each shipment to support your quality assurance protocols.

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); allow the sealed vial to equilibrate to room temperature before opening to avoid condensation.
