Description

D-Alanine, 1-Methylpropyl Ester (9Ci) is a chiral, non-proteinogenic amino acid derivative, specifically the ester form of D-alanine. This compound is a valuable chiral building block and intermediate in advanced organic synthesis, prized for its role in introducing stereochemical complexity. It is primarily utilized by research institutions and industrial R&D departments focused on pharmaceuticals, agrochemicals, and specialty materials where precise stereochemistry is critical for biological activity or material properties.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of peptidomimetics, antibiotics, and enzyme inhibitors.
• Agrochemical Research: Used in the development of chiral pesticides and herbicides, where the D-configuration can influence biological selectivity and environmental degradation profiles.
• Peptide Chemistry: Serves as a protected or modified amino acid residue in the solid-phase and solution-phase synthesis of non-natural peptides and peptide analogs.
• Ligand and Catalyst Development: Employed as a precursor for creating chiral ligands used in asymmetric catalysis, such as in hydrogenation or cross-coupling reactions.
• Biochemical Research: Used as a substrate or inhibitor in enzymatic studies to probe the activity and specificity of enzymes like D-amino acid oxidases or racemases.
• Material Science: A potential monomer or building block for synthesizing chiral polymers and functional materials with specific optical properties.
