Quality Control

Our Fozivudine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification (IR, HPLC), assay (HPLC), and impurity profiling, to ensure it meets high-purity standards suitable for research and development. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 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 using desiccants.
