Description

D-Alanine, (1S)-1,2-Dimethylpropyl Ester (9Ci) is a chiral, non-proteinogenic amino acid derivative, specifically an ester of D-alanine. This compound is a valuable synthetic intermediate and building block in organic and medicinal chemistry, prized for its role in introducing the D-alanine moiety into more complex molecular architectures. It is primarily utilized by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs), peptide mimetics, and chiral catalysts.

Application

• Pharmaceutical Intermediate: A key chiral building block for the synthesis of novel Active Pharmaceutical Ingredients (APIs), particularly in antibiotic and peptidomimetic research.
• Peptide Chemistry: Used in the preparation of modified peptides and peptide analogs where the D-alanine configuration is required for biological activity or metabolic stability.
• Asymmetric Synthesis: Serves as a chiral auxiliary or starting material in stereoselective synthesis to construct complex molecules with defined stereochemistry.
• Biochemical Research: Employed in enzymatic studies and as a substrate or inhibitor for enzymes that interact with D-amino acids.
• Material Science: Potential monomer or modifier in the synthesis of specialized polymers and functional materials.
