Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its aldehyde and ester functional groups allow for versatile chemical transformations, such as condensation reactions and nucleophilic substitutions, making it valuable in constructing complex aromatic frameworks. Commonly employed in the development of agrochemicals and dyes due to its ability to form stable derivatives with nitrogen- and sulfur-containing compounds. Also utilized in research settings for the preparation of heterocyclic compounds through cyclization reactions.
