Quality Control

Our Pentafluorophenyl 2,3-Dichloro-Benzenesulfonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and KF titration for moisture content, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic data are provided with every 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 (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
