Quality Control

Our 14-Methylfecosterol is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including identity confirmation by spectroscopic methods and purity assessment by chromatographic techniques. A Certificate of Analysis (COA) detailing specific results for purity, identity, and related substances is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
