Quality Control

Our Bis-γ-Glutamylcystine is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity verification and identity confirmation by spectroscopic methods, to ensure it meets high-purity research and development standards. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment to guarantee traceability and batch-to-batch consistency.

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. For long-term stability, consider storing under an inert atmosphere to prevent oxidation.
