Quality Control

Our Potassium (3-(tert-Butyl)-1-Methyl-1H-Pyrazol-5-Yl)Trifluoroborate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including NMR (1H, 13C, 19F, 11B), HPLC, and KF titration, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with full analytical data are provided for each lot to support your quality assurance and regulatory needs.

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). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for prolonged exposure to ensure long-term stability.
