Quality Control

Our 3,5-Dichloro-2-Hydroxybenzenesulfonyl Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay, purity profiling, and identification, to ensure it meets exacting standards for industrial and research applications. A Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
