Quality Control

Every batch of 1,1-Bis(Trifluoromethyl)-2,2,2-Trichloroethyl Methanesulfonate is produced and tested under a strict quality management system. We ensure high purity and consistency through advanced analytical techniques including HPLC, GC, NMR, and Karl Fischer titration. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 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) after opening to prevent degradation. Keep away from strong acids and incompatible organic solvents.
