Quality Control

Our (H-Cys-Phe-Oh)2 is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC for purity, chiral analysis, and identity confirmation to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment, ensuring full traceability and compliance with your internal quality protocols.

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 tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
