Quality Control

Our Benzoic Acid, 4-Amino-2,5-Difluoro-3-Methyl-, Methyl Ester (9Ci) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency meet the stringent requirements of our global clientele. Certificates of Analysis (COA) detailing all specifications are provided with each shipment and are 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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
