Quality Control

Our 5-(Trifluoromethyl)-5H-Thianthren-5-Ium Trifluoromethanesulfonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure high purity and batch-to-batch consistency suitable for research and industrial applications. Certificates of Analysis (COA) detailing all specifications are available upon request.

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 sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation.
