Quality Control

Our H-Glu-Trp-Oh is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification, chiral analysis to confirm stereochemical integrity, and identity confirmation via spectroscopic methods. Certificates of Analysis (COA) detailing all specifications and test results are provided to ensure traceability and compliance with your research or production requirements.

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.
