Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) active compounds. Its structure supports the creation of molecules with potential neuroprotective or neuromodulatory effects. It is also employed in medicinal chemistry research for designing inhibitors targeting specific enzymatic pathways. Due to its carboxylic acid functionality and fused ring system, it serves as a building block in heterocyclic chemistry for generating novel bioactive molecules.
