Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its aldehyde and ester functional groups allow for diverse reactions, such as condensation, reduction, and cyclization, making it valuable in constructing complex molecules. Commonly employed in the development of active pharmaceutical ingredients (APIs) where aromatic aldehydes are needed. Also utilized in the synthesis of heterocyclic compounds, including certain benzofurans and indoles, which are important scaffolds in medicinal chemistry. Its reactivity supports use in cross-coupling reactions and multistep synthetic routes in research laboratories and industrial settings.
