Quality Control

Every batch of 3-Methyl-2,3-Dihydro-1-Benzofuran-5-Sulfonyl Chloride is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the high standards required for research and process chemistry. A detailed Certificate of Analysis (COA) is supplied with each shipment, confirming identity, purity, and conformance to agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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) after opening to prevent decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
