Quality Control

Our production of 5-Methylfuran-2-Sulfonyl Chloride adheres to stringent quality management protocols. Each batch is rigorously analyzed using advanced techniques such as HPLC, GC, and NMR to ensure high chemical purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

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 decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, amines, and alcohols.
