Used as a chiral building block in the synthesis of pharmaceutical intermediates, particularly in the development of central nervous system (CNS) agents and serotonin receptor modulators. Its fluorinated chromane structure enhances metabolic stability and bioavailability in drug candidates. Commonly employed in asymmetric synthesis to introduce stereochemical control in active pharmaceutical ingredients (APIs). Also utilized in research for designing enzyme inhibitors due to its carboxylic acid functionality and rigid cyclic framework.
