Quality Control

Every batch of our 2,6-Dichloro-3-Methylbenzene-1-Sulfonyl Chloride undergoes rigorous quality testing to ensure compliance with stringent industry standards. We employ advanced analytical techniques including HPLC, GC, and NMR to verify identity, purity, and impurity profiles. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing all relevant specifications. Our quality management system is designed to meet the demands of cGMP and ISO standards for reliable and traceable supply.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent derivative, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, amines, and alcohols.
