Quality Control

Our 1-o-Benzyl-2C-Methyl-3,4-Isopropylidine-D-Ribopyranoside is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral integrity, NMR for structural confirmation, and KF for moisture content, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with full traceability are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation by atmospheric moisture. For long-term storage, consider using desiccants.
