Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its aldehyde and ester functional groups allow for versatile chemical transformations, such as condensation reactions and nucleophilic additions, making it valuable in constructing complex molecules. Commonly employed in the development of herbicides and plant growth regulators due to its structural similarity to bioactive aromatic compounds. Also utilized in the synthesis of dyes and fragrances where aromatic aldehyde derivatives are required.
