Quality Control

Our Benzenesulfonyl Chloride, 4-Propoxy- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and spectroscopic identification (IR, NMR), to ensure it meets exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic and strong acid/organic solvent nature, the container must be kept tightly sealed to exclude moisture and stored separately from bases and oxidizing agents.
