Quality Control

Our ε-n-(2-Furoyl-Methyl)-L-Lysine 2Hcl is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, chiral analysis, and identity confirmation, to ensure it meets the high standards required for research and pharmaceutical applications. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical characteristics 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a low-humidity environment. For long-term storage, consider desiccants or inert atmosphere.
