Description

n-Boc-N'-Xanthyl-L-Asparagine is a protected derivative of the amino acid L-asparagine, featuring both tert-butoxycarbonyl (Boc) and xanthyl (Xan) protecting groups. This compound matters as a crucial, high-purity building block in the synthesis of complex peptides and peptidomimetics, offering precise control over reaction pathways. It is primarily needed by research institutions and pharmaceutical companies engaged in advanced peptide chemistry, solid-phase peptide synthesis (SPPS), and the development of novel therapeutic agents.

Application

• Key intermediate in the solid-phase peptide synthesis (SPPS) of complex peptide sequences.
• Building block for the research and development of pharmaceutical peptides and bioactive compounds.
• Used in the synthesis of peptidomimetics for drug discovery programs.
• Valuable reagent in organic synthesis laboratories for introducing protected asparagine residues.
• Intermediate for creating custom amino acid derivatives and specialized monomers.
• Starting material in academic research exploring peptide structure-activity relationships.
