Fmoc-Cys(Trt)-OH-d2（Cat No.:S000718） is a deuterated form of Fmoc-Cys(Trt)-OH, where two hydrogen atoms are replaced with deuterium, enhancing its molecular stability. This modification is particularly useful as an internal standard for precise analytical methods like mass spectrometry and NMR spectroscopy. Fmoc-Cys(Trt)-OH is a cysteine derivative protected with a fluorenylmethyloxycarbonyl (Fmoc) group and a trityl (Trt) group, which protects the thiol side chain. The deuteration of Fmoc-Cys(Trt)-OH-d2 facilitates more accurate pharmacokinetic and metabolic studies, allowing researchers to study the stability and behavior of cysteine residues in peptide synthesis and processing.
