Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex pyrimidine-based structures found in pharmaceuticals and agrochemicals. Its boronic ester group facilitates efficient carbon-carbon bond formation under mild conditions, making it valuable in drug discovery for building biaryl scaffolds. Commonly employed in the development of kinase inhibitors and other bioactive molecules due to the prevalence of phenylaminopyrimidine motifs in such compounds. Stable and compatible with a wide range of functional groups, it supports high-yielding transformations in both research and industrial settings.
