Quality Control

Our Cycloheptanesulfonyl Chloride is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and Karl Fischer titration for moisture content. We provide a detailed Certificate of Analysis (COA) with each shipment, ensuring traceability and compliance with your research or production specifications. Our quality commitment supports applications requiring high-purity intermediates for regulated industries.

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 degradation. Keep away from strong acids, bases, and oxidizing agents.
