Quality Control

Our Potassium (3-Methoxyphenyl)Trifluoroborate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including NMR (1H, 11B, 19F) and HPLC analysis, to ensure high chemical purity and consistent performance in sensitive coupling reactions. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request 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 inert atmosphere (e.g., nitrogen or argon) when prolonged exposure is necessary to maintain optimal purity and reactivity.
