Quality Control

Our Cytidine, 5-Hydroxy- is manufactured under a quality management system and undergoes rigorous analytical testing to ensure batch-to-batch consistency and high purity. Standard quality parameters include identification, assay, and impurity profile analysis using techniques such as HPLC, NMR, and mass spectrometry. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container should be kept in a desiccated environment to maintain product integrity. For long-term storage, consider conditions of 2-8°C.
