Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. Its ester groups allow for selective hydrolysis or transesterification, enabling the introduction of functionalized aromatic building blocks. Commonly employed in the development of polymers and specialty monomers due to the rigid phenylene core, which can enhance thermal and mechanical properties. Also utilized in research settings for constructing complex molecules where a para-substituted benzene ring with flexible acetate spacers is required.
