Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs). Its structure allows for selective functionalization, making it valuable in constructing complex aromatic systems. Commonly employed in organic reactions where a chloro-substituted benzoic acid derivative with a protected hydroxyl group is required. The benzyl ether group can be deprotected under mild conditions, enabling stepwise synthesis in drug discovery and medicinal chemistry research.
