Quality Control

Our 7,9-Dimethylguanine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis to ensure it meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing all specifications 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.
