Quality Control

Our 2-Chloro-5-(1-Chloro-1,3-Dihydro-3-Oxo-1-Isobenzofuranyl)Benzenesulphonyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for use in sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and compliance.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from incompatible materials such as strong bases, amines, and alcohols.
