Used as a key 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 reactive sulfonyl and chloro groups. The compound is also employed in research settings for the preparation of pyrimidine-based derivatives with potential biological activity. Its versatility in cross-coupling reactions makes it valuable in medicinal chemistry for constructing complex molecules.
