Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of local anesthetics such as lidocaine and related derivatives. It contributes to the lipophilic character of the final drug molecule, enhancing tissue penetration and duration of action. Also employed in the development of anti-inflammatory agents and other bioactive compounds where aryl acetic acid structures are required. Its structural properties make it valuable in medicinal chemistry for optimizing metabolic stability and target binding.
