(S)-1-(2,3-Difluorophenyl)ethanamine is primarily used as a chiral building block in the synthesis of pharmaceutical compounds. Its structure, featuring a stereocenter and fluorinated aromatic ring, makes it valuable in the development of drugs targeting neurological disorders, such as antidepressants and antipsychotics. The compound’s fluorinated moiety enhances its ability to interact with biological targets, improving metabolic stability and bioavailability. Additionally, it is employed in the production of ligands for asymmetric catalysis, aiding in the creation of enantiomerically pure substances. Its applications extend to research in medicinal chemistry, where it serves as an intermediate in the design of novel therapeutic agents.
