Quality Control

Every batch of 3-(2-Methylphenoxy)Benzenesulphonyl Chloride is manufactured and tested under a strict quality management system. We ensure the product meets high-purity standards suitable for research and commercial synthesis. Comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, is performed to verify identity and purity. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your specifications.

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 hydrolysis. Keep away from strong bases, oxidizing agents, and sources of ignition.
