Quality Control

Our L-γ-Glutamyl-S-[(4-Hydroxyphenyl)Methyl]-L-Cysteinylglycine is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and MS for structural confirmation, and tests for residual solvents and heavy metals to ensure it meets the stringent requirements of research and development applications. Certificates of Analysis (COA) documenting all specifications are provided with every shipment.

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 storing under an inert atmosphere.
