Quality Control

Our 4-Isopropylbenzenesulfonyl Chloride is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing specific results for purity, appearance, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and amines.
