Quality Control

Our 2-Chloroethanesulphonyl Isocyanate is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling by gas chromatography (GC) or HPLC, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific test results is provided with every shipment to guarantee compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a temperature between 2°C and 8°C (refrigerated). 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 from atmospheric moisture.
