Fmoc-Met-OH-d3（Cat No.:S000728） is a deuterated version of Fmoc-Met-OH, where three hydrogen atoms in the methyl group of the methionine side chain are replaced with deuterium. This modification enhances its molecular stability, making it highly suitable for use as an internal standard in analytical methods like mass spectrometry and NMR spectroscopy. Protected by the fluorenylmethyloxycarbonyl (Fmoc) group, this methionine derivative is frequently utilized in peptide synthesis. The incorporation of deuterium in Fmoc-Met-OH-d3 facilitates more precise pharmacokinetic and metabolic studies, aiding researchers in investigating peptide behaviors and interactions in biological systems.
