Used as a key 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 halogenated pyrimidine structure, which allows for selective cross-coupling reactions. Commonly employed in the preparation of biologically active molecules targeting tyrosine kinases and other enzyme systems involved in cell signaling pathways. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
