L-ASPARAGINE-N-FMOC, N-BETA-TRITYL (15N2) is a protected amino acid derivative of L-asparagine in which the amino functionality is substituted with an Fmoc group and a β-trityl (trityl-type) protecting group, and the side chain retains the amide functionality characteristic of asparagine. The molecule bears a free carboxyl group and two isotopically labeled nitrogen atoms (15N2) within the asparagine nitrogen-containing positions, while the protected amine sites are rendered less nucleophilic by the bulky protecting groups to control chemoselectivity during peptide assembly. In synthetic and analytical research, this 15N-labeled, orthogonally protected building block is used for solid-phase or solution-phase peptide synthesis and for preparing labeled peptide or protein fragments to support isotopic tracing, mass spectrometric method development, and structure-property studies.
