Quality Control

Our 5-Fluoro-3-(2-Methoxyphenyl)Benzoic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical R&D and fine chemical synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
