Quality Control

Our Potassium (5-Bromothiophen-2-Yl)Trifluoroboranuide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (1H, 13C, 11B, 19F), HPLC, and elemental analysis, to ensure high purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing all specifications are provided and available upon request.

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 compound is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (argon/nitrogen) for long-term stability and to prevent decomposition. Keep away from incompatible materials.
