Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its carbonate ester group enables controlled reactivity in coupling reactions, making it valuable for constructing complex molecules. It is also employed in the development of prodrugs, where the amyl and carboxyphenyl moieties can influence solubility and release characteristics. Additionally, it finds use in polymer chemistry as a monomer or protecting group due to its thermal and hydrolytic stability under specific conditions.
