Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) requiring substituted phenylacetic acid derivatives. Its halogenated aromatic structure makes it valuable for cross-coupling reactions in medicinal chemistry, enabling the construction of complex molecules for drug discovery. Commonly employed in the preparation of analgesic, anti-inflammatory, or neuroactive agents where specific halogen positioning influences biological activity. Also utilized in research settings to design and optimize synthetic routes involving selective functionalization of aromatic systems.
