Quality Control

Our n-Butyldi(tert-Butyl)Phosphonium Tetrafluoroborate is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and ion chromatography, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are provided to guarantee compliance with your research and production requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from incompatible materials such as strong bases and fluorides.
