Fmoc-Met-OH is widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected form of methionine, where the Fmoc group acts as a temporary protecting group for the amino group. This allows for the stepwise assembly of peptides on a solid support. The compound is essential in creating peptides with methionine residues, ensuring precise control over the sequence and structure. It is also utilized in the development of pharmaceuticals, bioactive peptides, and research applications where specific peptide sequences are required. The Fmoc group can be easily removed under mild basic conditions, making it a convenient choice for peptide synthesis workflows.
