Quality Control

Our Sulfuryl Chloride is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing key parameters such as assay, color, and specific impurity limits. Our quality management system is designed to meet the rigorous demands of industrial and fine chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases, amines, and alcohols. Due to its highly volatile and strong acid/organic solvent nature, containers must be kept tightly sealed and upright to prevent moisture ingress and fume release. Recommended storage temperature is between 15°C to 25°C.
