Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of sulfonylurea herbicides. It plays a key role in creating active compounds that inhibit plant growth by targeting specific enzymes in weeds. Also employed in the development of certain antimicrobial agents and in research for novel drug candidates due to its reactive amino and chloro groups, which allow for further chemical modifications. Commonly utilized in heterocyclic chemistry for building more complex pyrimidine-based structures.
