Used primarily as an intermediate in the synthesis of pharmaceuticals, especially non-steroidal anti-inflammatory drugs (NSAIDs). It serves as a chiral building block in the production of active enantiomers for drugs with improved efficacy and reduced side effects. Also employed in the development of agrochemicals and fragrances due to its aromatic structure and functional reactivity. Its derivatives can be found in some herbicides and plant growth regulators. Additionally, it is used in research settings for racemization studies and asymmetric synthesis methods.
