Description

Z-Orn-Oh CAS NO 2640-58-6 is a high-purity, non-proteinogenic amino acid derivative, specifically the benzyloxycarbonyl (Z or Cbz) protected form of ornithine. This compound is a critical building block in peptide synthesis, offering a protected side chain amine that enables selective deprotection and controlled chain elongation. It is essential for researchers and manufacturers in the pharmaceutical and biotechnology sectors, particularly for developing novel peptide-based therapeutics, diagnostic agents, and biochemical tools.

Application

• Solid-Phase Peptide Synthesis (SPPS): A key protected intermediate for the controlled incorporation of ornithine into peptide sequences.
• Solution-Phase Peptide Chemistry: Used in the synthesis of complex peptides and peptidomimetics where selective deprotection strategies are required.
• Bioconjugation and Linker Chemistry: Serves as a versatile spacer or functional handle for attaching peptides to other molecules, surfaces, or solid supports.
• Research & Development: A fundamental reagent in academic and industrial R&D for studying protein-protein interactions, enzyme substrates, and signal transduction pathways.
• Production of Specialty Peptides: Used in the manufacture of antimicrobial peptides (AMPs), cell-penetrating peptides (CPPs), and other bioactive peptides with therapeutic potential.
• Biochemical Tool Development: Employed in creating affinity tags, enzyme inhibitors, and molecular probes for biological assays.
