L-Proline-d3-N-Fmoc（Cat No.:R061076） is a deuterated version of L-Proline, where three hydrogen atoms are replaced with deuterium, and it is protected with a fluorenylmethyloxycarbonyl (Fmoc) group. This isotopic labeling and protection enhance its stability and utility in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) where Fmoc protection is standard. The deuterium atoms reduce isotopic scrambling and improve the detection accuracy in mass spectrometry, crucial for confirming peptide structures and compositions.
