Quality Control

Our 3-[3-Fluoro-4-Methoxyphenyl)Sulphonyl]Propanoic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure compliance with exacting R&D and production standards. Certificates of Analysis (COA) detailing all specifications are available upon request, and we support custom purity grades to meet specific project requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
