Quality Control

Our H-Met-Lys-Oh Formiate Salt is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity, chiral analysis, and residual solvent screening, to ensure it meets the stringent requirements for peptide synthesis. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment and are available upon request.

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 dry environment to prevent absorption of moisture. For long-term storage, consider desiccants or inert atmosphere.
