Quality Control

Our 2,6-Dibromo-4-Methylbenzene-1-Sulfonyl Chloride is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity, identity, and impurity profiles 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 and moisture-sensitive nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases, oxidizing agents, and sources of ignition.
