Quality Control

Every batch of our 1,2,5-Thiadiazolidine-2-Carbonyl Chloride, 5-Methyl-, 1,1-Dioxide is produced and tested under strict quality management systems. We ensure high purity and consistency through advanced analytical techniques including HPLC, NMR, and IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong acids and incompatible organic solvents.
