Fmoc-L-Methionine (Fmoc-Met-OH) (CAS: 71989-28-1) is an N-Fmoc-protected form of L-Methionine. It is widely used as a protecting group during peptide synthesis. The Fmoc group is added temporarily to the N-terminus of the amino acid sequence, which protects it during the synthesis process. After synthesis, the Fmoc group can be removed using an appropriate reagent, leaving the desired peptide product.
Fmoc-L-Methionine is used in peptide synthesis, used as an organic synthesis intermediate, pharmaceutical intermediate, biochemical reagent.
Fmoc-L-Methionine is also used in the synthesis of peptide-based drugs, as it can be used to modify the structure of peptides to increase their bioavailability. Additionally, Fmoc-L-Methionine can be used in the synthesis of peptide-based vaccines, as it can be used to modify the structure of peptides to increase their immunogenicity.
