Quality Control

Our Potassium 5-Formylthiophen-3-Yltrifluoroborate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR (1H, 13C, 19F, 11B) and HPLC analysis, to ensure high chemical purity and consistent performance in cross-coupling reactions. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment 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 area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect product stability and reactivity. Keep away from incompatible materials.
