Quality Control

Our 3-Bromothiophene-2-Sulphonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and scale-up applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

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 strong acid/organic solvent nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as bases and oxidizing agents.
