Quality Control

Our Cyclo(Tyrosyl-Tyrosyl) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and spectroscopic identification, to ensure it meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing specific results is 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 (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container should be kept in a low-humidity environment and sealed immediately after use to prevent degradation.
