Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of nonsteroidal anti-inflammatory drugs (NSAIDs). It serves as a key building block in the preparation of fenbufen and related compounds due to its ability to undergo ester hydrolysis and decarboxylation reactions. Its nitro and carboxyl functional groups allow for further chemical modifications, making it valuable in organic synthesis for constructing complex aromatic structures. Also employed in the development of dyes and agrochemicals where nitroaromatics are required.
