Quality Control

Our Cyclo(Glycyl-Prolyl-Psi(Ch2So)-Glycyl-Phenylalanyl-Prolyl) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, MS for identity confirmation, and NMR for structural verification, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry, controlled environment. Due to its hygroscopic nature, the product should be handled under anhydrous conditions or a dry inert atmosphere to maintain stability and purity. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
