Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients that require substituted benzaldehyde derivatives. Its functional groups allow for selective reactions, making it valuable in creating complex organic molecules. Commonly employed in the production of herbicides and fungicides due to its reactivity and structural properties. Also utilized in research laboratories for the preparation of heterocyclic compounds and in the construction of more complex aldehydes through cross-coupling reactions.
