Quality Control

Every batch of Dimethylaminosulphinyl Chloride is produced and tested under stringent quality management protocols to ensure consistency and reliability for your critical processes. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as purity, identity, and impurity profiles. Our quality systems are designed to support applications requiring high-purity intermediates, including those under development for regulatory submission.

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, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. 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, alcohols, and water.
