Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to participate in cross-coupling reactions, enabling the construction of complex heterocyclic systems. Also employed in the preparation of organic semiconductors and fluorescent dyes owing to its extended aromatic structure and electron-deficient pyrimidine core. Its derivatives are explored in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
