Specification
Description
Fmoc-3,4-difluoro-L-phenylalanine is a non-natural amino acid that contains a substituted phenylalanine residue, which is characterized by the presence of two fluorine atoms on the 3 and 4 positions of the aromatic ring. This modification enhances the lipophilicity of the phenylalanine residue and provides unique steric and electronic properties compared to the natural phenylalanine. Fmoc-3,4-difluoro-L-phenylalanine is widely used in peptide synthesis, pharmaceuticals, and materials science due to its ability to form stable secondary structures, such as helices and beta-turns, in peptides and proteins.
