Quality Control

Our production of o-(Propylthio)Benzenesulphonyl Chloride adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity suitable for research and process applications. Each lot is analyzed using advanced techniques including HPLC, GC, and NMR spectroscopy. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 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 degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, amines, and alcohols.
