Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical synthesis. Particularly effective in constructing biaryl frameworks found in active pharmaceutical ingredients. Its fluorinated pyridyl structure enhances stability and reactivity with aryl halides under mild conditions, making it suitable for late-stage functionalization in drug development. Commonly applied in the preparation of kinase inhibitors and other nitrogen-containing heterocyclic compounds in medicinal chemistry.
