Quality Control

Our Ethenocytidine Hydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and moisture content. We provide full traceability and Certificates of Analysis (COA) are available upon request, ensuring compliance with research and development grade specifications.

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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider desiccants or an inert atmosphere.
