Quality Control

Our Trimethylsilylethynyl(Phenyl)Iodonium Tetrafluoroborate is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and elemental analysis, to ensure high chemical purity and consistent performance. A Certificate of Analysis (COA) detailing batch-specific results is provided with every shipment to guarantee compliance with your research and development specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label. This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to maintain stability and prevent decomposition.
