Quality Control

Our Pentane-1,5-Di(Sulfonyl Chloride) is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC, NMR, and titration to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical characteristics 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 degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, amines, and alcohols.
