Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its reactive chlorine atoms allow for selective substitution reactions, making it valuable in building complex organic molecules. Commonly employed in the development of herbicides and fungicides due to its ability to enhance bioactivity in final products. Also utilized in the preparation of dyes and functional materials where halogenated heterocycles improve stability and performance. Its versatility in cross-coupling reactions supports applications in medicinal chemistry for creating novel drug candidates.
