Used as a boron-based reagent in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. It serves as a stable, air- and water-tolerant source of arylboron equivalents, enabling the introduction of the 3,4-dichlorophenyl group into aromatic, heteroaromatic, and other electrophilic substrates. This is valuable in pharmaceutical and agrochemical industries for constructing complex molecules with enhanced properties such as metabolic stability and bioactivity. The reagent is especially effective under mild, aqueous conditions, allowing selective C-C bond formation without degrading sensitive substrates. Its potassium counterion enhances solubility in polar and aqueous solvents, improving reaction efficiency in various cross-coupling processes.
