Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building pyrimidine-based drug candidates. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to introduce aryl or amino groups, enabling the construction of complex molecules for drug discovery research. Also utilized in agrochemicals for the design of novel pesticides and herbicides due to its ability to modulate biological activity in target organisms.
