Quality Control

Our 2-[4-(4-Ethyl-Benzenesulfonyl)-Phenyl]-5-Methyl-2H-Pyrazol-3-Ylamine is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC and NMR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

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