Quality Control

Our 4-Isopropoxybenzenesulfonyl Chloride is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all relevant specifications. Our quality systems are designed to support cGMP and ISO standards for reliable supply to regulated industries.

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 and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong bases, oxidizing agents, and sources of heat.
