Used primarily as a key intermediate in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly in the production of diclofenac and related derivatives. Its structure allows for efficient transformation into active pharmaceutical ingredients through ester hydrolysis and subsequent coupling reactions. It is also employed in organic synthesis for building complex aromatic compounds due to the reactivity of the ester group and the halogenated aromatic ring. Its stability and solubility properties make it suitable for use in multi-step reactions under various catalytic conditions.
