Quality Control

Our H-Tyr-Thr-Lys-Oh is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and MS for identity confirmation, to ensure it meets high-purity standards suitable for research and development. Certificates of Analysis (COA) with detailed chromatographic data 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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider desiccants or inert atmosphere.
