Quality Control

Our Cholesteryl Linolenate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the stringent requirements for research and formulation. A Certificate of Analysis (COA) detailing batch-specific results is provided with every shipment.

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.
