Quality Control

Our H-Trp-Ser-Oh is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and pharmaceutical applications. Certificates of Analysis (COA) with detailed batch-specific 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.
