Used as a reagent in organic synthesis, particularly in trifluoromethylation reactions. It enables the introduction of CF3 groups into aromatic and heteroaromatic compounds, which is valuable in pharmaceutical and agrochemical development due to the metabolic stability and lipophilicity imparted by the trifluoromethyl group. Its potassium salt form enhances solubility and handling compared to other boron-based reagents. Commonly applied in late-stage functionalization of complex molecules, allowing for efficient modification of bioactive compounds without degrading sensitive functional groups.
