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 the preparation of biologically active molecules due to its halogenated pyrimidine structure, which allows for selective cross-coupling reactions. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug candidates. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
