Quality Control

Our C18 Ceramide (D17:1/18:0) is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure compliance with high-purity standards suitable for research and development. Certificates of Analysis (COA) detailing all specifications are available upon request.

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, as the compound is easily oxidized and light-sensitive. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
