Quality Control

Our H-Tyr-Tyr-Tyr-Oh is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, mass spectrometry for identity confirmation, and chiral purity analysis to ensure it meets the stringent requirements for research and development. A detailed Certificate of Analysis (COA) documenting all test results 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 sealed in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
