Quality Control

Our Cysteinylproline is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets high-purity standards suitable for research and development. Certificates of Analysis (COA) with detailed batch-specific results 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 after opening to minimize exposure to atmospheric humidity. For long-term storage, consider using desiccants or storing under an inert atmosphere to prevent oxidation.
