Description

(2S)-2-Amino-3-Phenyl-Propanoic Acid is the L-enantiomer of phenylalanine, a fundamental aromatic amino acid. This high-purity chiral building block is essential for synthesizing peptides and pharmaceutical intermediates where stereochemical integrity is critical. It is primarily required by research institutions and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors for applications in drug discovery and development.

Application

• Pharmaceutical Intermediate: A key chiral precursor in the synthesis of peptide-based drugs, enzyme inhibitors, and other active pharmaceutical ingredients (APIs).
• Biochemical Research: Used in cell culture media formulation, metabolic studies, and as a standard in analytical chemistry for amino acid analysis.
• Peptide Synthesis: Serves as a critical building block in solid-phase and solution-phase peptide synthesis for research and therapeutic peptides.
• Nutraceuticals & Supplements: Employed in the production of specialized dietary supplements and infusion solutions where the specific L-form is biologically active.
• Asymmetric Catalysis: Utilized as a chiral ligand or auxiliary in asymmetric synthesis to induce stereoselectivity in chemical reactions.
• Reference Standard: Acts as a high-purity certified reference material (CRM) for quality control and analytical method development in pharmaceutical laboratories.
