Used in organic synthesis as a building block for pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs). It serves as a key intermediate in the creation of compounds with potential therapeutic effects, such as anti-inflammatory, antiviral, or anticancer agents. Its unique structure allows for modifications that enhance drug efficacy and selectivity. Additionally, it is employed in research to study the biological activity of fluoro-substituted indene derivatives, aiding in the discovery of new drug candidates.
