Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. It serves as a building block in the development of ester-based prodrugs due to its biodegradable ester linkage and aromatic structure. Also employed in the synthesis of liquid crystals and functional polymers, where its phenolic and ester functionalities allow for further chemical modifications. Its derivative structure supports applications in UV-absorbing compounds and optical brighteners in specialty materials.
