Quality Control

Our 1-Chloro-2-(Chloromethylsulfonyloxy)Ethane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity suitable for research and industrial synthesis. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity, and impurity profiles. Our quality management system supports compliance with cGMP and ISO standards where required.

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) after opening to prevent degradation. Keep away from strong bases and incompatible organic solvents.
