Quality Control

Our C17 Dihydro Ceramide is manufactured under strict quality systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via NMR and mass spectrometry, to ensure it meets the high standards required for research and formulation. Certificates of Analysis (COA) with detailed chromatographic data are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation. Allow the product to equilibrate to room temperature in a desiccator before opening to minimize moisture uptake.
