Quality Control

Our Potassium 4-Chlorophenyltrifluoroborate is manufactured under strict quality protocols. Each batch undergoes comprehensive analytical testing, including NMR (1H, 11B, 19F) and HPLC analysis, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory 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). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to maintain stability and purity.
