Quality Control

Our Potassium Trifluoro(3-(4-Methoxyphenyl)-1H-Pyrazol-5-Yl)Borate is manufactured under strict quality management systems. Each 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 detailed specifications are provided and can be tailored to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Optimal storage temperature is 2-8°C.
