Widely used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in agrochemicals, contributing to the creation of herbicides and fungicides due to its stable pyrimidine core and reactive halogen sites. Its structure allows for selective substitution reactions, making it valuable in medicinal chemistry for optimizing drug potency and selectivity. Also employed in research for developing novel organic materials and catalysts.
