Used as a key intermediate in the synthesis of biologically active compounds, particularly in the development of kinase inhibitors for cancer therapy. Shows potential in medicinal chemistry for targeting tyrosine kinases involved in tumor growth and signal transduction pathways. Also employed in research settings to design novel quinazoline-based pharmaceuticals with enhanced selectivity and potency. Its bromo and methyl functional groups allow for further chemical modifications, enabling the creation of diverse compound libraries for drug discovery.
