Used as an intermediate in organic synthesis, particularly in the preparation of functionalized aromatic compounds for pharmaceuticals and advanced materials. Its ester groups allow for selective hydrolysis or transesterification, enabling stepwise construction of complex molecules. The benzyl-protected hydroxy group can be deprotected under mild conditions, making it valuable in multi-step syntheses where orthogonality is required. Commonly employed in the development of ligands, polymers, and bioactive molecules requiring precise substitution patterns on the aromatic ring.
