Quality Control

Our Fosteabine Sodium is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and related substances, identity confirmation by IR and NMR, and residual solvent analysis. We provide full traceability and Certificates of Analysis (COA) are supplied with every shipment, ensuring compliance with cGMP guidelines for pharmaceutical intermediates.

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 inert atmosphere.
