Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and plant growth regulators. Its structure enables selective reactivity in building active ingredients that target specific enzyme pathways in weeds. Also employed in medicinal chemistry for developing kinase inhibitors due to the pyrimidine core’s affinity for biological targets. The sulfonyl and chloro groups allow further functionalization, making it valuable in multi-step organic synthesis for pharmaceuticals and crop protection agents.
