Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and plant growth regulators. Its structure allows for selective functionalization, making it valuable in constructing nitrogen-containing heterocyclic compounds. It is also employed in the preparation of kinase inhibitors and other bioactive molecules in medicinal chemistry research. Due to the presence of reactive aldehyde and halogen groups, it facilitates cross-coupling reactions and condensation processes in organic synthesis.
