Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to its reactive pyrimidine core and functional groups that allow further chemical modifications. Its structure supports the development of compounds with selective activity against weeds and pests. Also employed in medicinal chemistry for constructing biologically active molecules, including kinase inhibitors and other pharmaceuticals targeting inflammatory and oncological pathways. The methylsulfonyl group enhances solubility and binding affinity, making it valuable in designing potent and stable drug candidates.
