Quality Control

Our H-Thr-Lys-Tyr-Oh is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and MS for identity confirmation, to ensure it meets high-purity standards suitable for research and synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key specifications such as assay, chiral purity, and related substances.

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.
