Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its structure allows for further chemical modifications, making it valuable in developing compounds with specific biological activity. Also employed in the preparation of dyes and agrochemicals due to its aromatic and functional group characteristics. Its hydroxyl and carboxylic acid groups enable esterification and coupling reactions important in organic synthesis.
