Quality Control

Our Fc131 Tfa (Free Base) is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including HPLC for purity assessment and MS for identity confirmation. A comprehensive Certificate of Analysis (COA) detailing all test results and specifications is provided with each batch to support your quality assurance and regulatory documentation needs.

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. For long-term stability, consider storage at -20°C under inert atmosphere.
