Quality Control

Our 1,1,2,2-Tetrafluoroethylthioacetic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and GC, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality parameters. We support compliance with REACH and other global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Keep away from strong bases, oxidizing agents, and sources of ignition. Due to its nature as a strong acid/organic solvent, handle with appropriate personal protective equipment in a fume hood.
