Description

D-Arginine Amide Dihydrochloride is a high-purity, non-natural enantiomer of the amino acid arginine, widely utilized in advanced pharmaceutical research and development. This compound serves as a critical chiral building block and intermediate for the synthesis of novel peptide-based therapeutics and diagnostic agents. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors who require high-fidelity, optically pure components for drug discovery and process chemistry.

Application

• Pharmaceutical Intermediate: A key chiral precursor in the synthesis of peptide drugs, enzyme inhibitors, and receptor antagonists.
• Biochemical Research: Used in proteomics and enzymology studies to investigate enzyme-substrate interactions and metabolic pathways.
• Peptide Synthesis: Serves as a protected arginine derivative in solid-phase and solution-phase peptide synthesis (SPPS).
• Diagnostic Reagent Development: Employed in the formulation of specialized reagents and buffers for clinical diagnostics.
• Asymmetric Catalysis: Acts as a ligand or chiral auxiliary in asymmetric synthesis to induce stereoselectivity.
• Reference Standard: Used as an analytical standard in HPLC and LC-MS for quality control and method validation in pharmaceutical analysis.
