Quality Control

Our 3-Ribofuranosylpyrazolo(3,4-E)(1,3)Oxazine-5,7-Dione is produced under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for research and development. All products undergo rigorous analytical testing, including HPLC for purity and spectroscopic identification (NMR, MS). A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your regulatory and research documentation needs.

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 should be kept in a desiccated environment. For long-term storage, consider storing under an inert atmosphere to maintain stability.
