Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its functional groups allow for selective transformations, making it valuable in constructing complex aromatic systems. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to introduce aryl or alkenyl substituents. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its stability and reactivity profile. Preferred in late-stage functionalization due to the presence of halogen atoms that enable further derivatization.
