Quality Control

Our δ-Carboxymethylcysteinyl-Cysteinyl-Valine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity verification and identity confirmation by spectroscopic methods, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed batch-specific data are available upon request to support your quality assurance 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.
