Fmoc-Met-OH, a vital component in peptide chemistry, is a crystalline solid used as a key building block for synthesizing peptides. This compound features the Fmoc (9-fluorenylmethoxycarbonyl) protecting group, allowing for selective protection of the methionine amino acid during peptide chain elongation. Its high purity and compatibility with solid-phase peptide synthesis make it an essential tool for researchers and professionals in the fields of pharmaceuticals, biochemistry, and biotechnology.
