Quality Control

Our 4-Ethoxy-3-(3-Pyridin-2-Yl-Ureido)-Benzenesulfonyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition.
