Description

L-Abrine CAS NO 526-31-8 is a high-purity, non-proteinogenic amino acid derivative, specifically the methyl ester of L-2-Amino-3-(4-hydroxyphenyl)propanoic acid. This compound serves as a critical chiral building block and intermediate in advanced organic synthesis, enabling the production of complex molecules with high stereochemical fidelity. It is essential for research and development laboratories, pharmaceutical manufacturers, and fine chemical producers focused on creating peptides, active pharmaceutical ingredients (APIs), and other bioactive compounds.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the synthesis of peptide-based drugs, enzyme inhibitors, and other therapeutic agents.
• Biochemical Research: Used as a specialized reagent in proteomics, enzymology studies, and metabolic pathway research.
• Asymmetric Synthesis: Employed as a building block for constructing complex natural products and novel chemical entities with defined stereochemistry.
• Agrochemical Development: Acts as an intermediate in the research and production of advanced, targeted pesticides and herbicides.
• Peptide Chemistry: Integral for the solid-phase and solution-phase synthesis of custom peptides for diagnostic and research applications.
