Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its structure supports the construction of bioactive molecules with potential application in treating neurological disorders. The amine functionality allows for further derivatization, enabling the formation of amide or sulfonamide bonds in drug design. Commonly employed in medicinal chemistry for building constrained heterocyclic scaffolds that enhance target selectivity and metabolic stability. Also utilized in the preparation of selective kinase inhibitors and receptor modulators due to its rigid dihydroisoquinoline core and fluorine substitution, which can improve binding affinity and pharmacokinetic properties.
