Quality Control

Our Ll-37 Fkr is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. All materials are subjected to comprehensive analytical testing, including HPLC for purity and MS for identity confirmation. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under dry conditions to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
