Quality Control

Our 4-[Methyl(Phenylsulfonyl)Amino]Benzoic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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.
