Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer therapy. Its structure allows for selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in Suzuki-Miyaura and other palladium-catalyzed reactions to introduce pyrimidine motifs into drug candidates. Also utilized in agrochemical research for designing bioactive molecules with improved stability and binding affinity.
