Quality Control

Our Acetylcysteinyl-Leucyl-Glutamyl-Glutamyl-Prolyl-Cysteine Methyl Ester Cyclic Disulfide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and MS for identity confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic data are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. Due to its hygroscopic (moisture-sensitive) nature, the container must be sealed under an inert atmosphere after each use to prevent degradation. For long-term storage, desiccants are recommended.
