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 ability to enhance binding affinity and selectivity toward specific enzyme targets. Commonly employed in the preparation of antitumor agents and antiviral drugs, especially in programs focused on targeted therapies. Its cyclopropyl-substituted pyrimidine core contributes to improved metabolic stability and pharmacokinetic properties in drug candidates.
