Quality Control

Every batch of S-(Fluoromethyl) Benzenesulfonothioate is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the compound meets the high-purity standards required for research and development applications. A detailed Certificate of Analysis (COA) is supplied with each shipment, confirming identity, purity, and impurity profile.

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 after opening. Keep away from incompatible materials such as strong bases and fluorides.
