Quality Control

Our R-Cytidine CAS NO 13913-16-1 is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis for enantiomeric excess, and identification by IR and NMR, to ensure it meets the high standards required for research and pharmaceutical applications. Certificates of Analysis (COA) with detailed batch-specific results are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider desiccants or inert atmosphere.
