Quality Control

Our 4-Ethoxyfluorophosphinyloxy Tempo is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and Karl Fischer titration for moisture content, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
