Quality Control

Our 5H-Purine (9Ci) is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and identity confirmation by spectroscopic methods, to ensure it meets the high standards required for research and industrial use. Certificates of Analysis (COA) documenting all critical parameters 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, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider the use of desiccants.
