Quality Control

Our production of this fluorinated specialty chemical adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Every lot is characterized using advanced analytical techniques, including NMR (¹H, ¹⁹F), HPLC, and GC-MS, to confirm identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and specific impurity profiles is provided with each shipment. We support compliance with ISO 9001 quality management standards and can tailor specifications to meet the rigorous demands of cGMP environments for pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its nature as a strong acid/organic solvent, keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents. Handle and store under an inert atmosphere if specified for high-purity grades to prevent moisture uptake or degradation.
