Quality Control

Our 5-Dehydroepisterol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and synthesis applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is light-sensitive and easily oxidized; for long-term storage, it is recommended to keep the container under an inert atmosphere (e.g., nitrogen or argon) to maintain stability and purity.
