Quality Control

Our production of 4,5-Dimethoxy-2-Methylbenzene-1-Sulfonyl Chloride adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications. We operate under a quality system designed to meet the demands of cGMP and ISO standards for critical intermediates.

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.
