Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and plant growth regulators. Its structure allows for selective modification in pesticide development, enhancing activity and stability. Also employed in pharmaceutical research for building blocks in nitrogen-containing heterocyclic compounds. Common in cross-coupling reactions due to the presence of chlorine, enabling formation of C–C and C–heteroatom bonds under palladium catalysis. Frequently utilized in the preparation of kinase inhibitors and other bioactive molecules.
