Quality Control

Our [1,2,5]Thiadiazolo[3,4-B]Pyrazine-5(3H)-Thione,6-Amino-(9Ci) is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR), to ensure it meets the high standards required for research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles 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 (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 using desiccants.
