(S)-1-[4-(Trifluoromethyl)phenyl]ethylamine (CAS 84499-73-0)

(S)-1-[4-(Trifluoromethyl)phenyl]ethylamine is a significant organic compound with wide-ranging applications. Derived from the amino acid phenethylamine, it serves as a precursor in the synthesis of various organic compounds. The remarkable feature of (S)-1-[4-(Trifluoromethyl)phenyl]ethylamine lies in its capacity to function as a molecular switch. Extensive research has explored its ability to transition between different conformations, yielding valuable insights. For instance, it has been utilized to investigate the impact of conformational changes on protein-ligand interactions. The molecular switch property of (S)-1-[4-(Trifluoromethyl)phenyl]ethylamine is attributed to its capability to exist in two distinct conformations known as the "cis" and "trans" forms. Among these, the cis form is considered more stable and predominantly observed in solution, while the trans form is relatively less stable and observed in the solid state. The presence of the trifluoromethyl group on the phenyl ring is believed to be responsible for the conformational switch between the two forms.
