Description

L-Alanine, (1S)-1,2-Dimethylpropyl Ester (9Ci) is a specialized chiral amino acid ester derivative, serving as a critical building block in advanced organic synthesis. Its value lies in providing a protected alanine moiety with a sterically hindered ester group, which can influence reaction pathways and final product properties. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical and fine chemical sectors, particularly for developing novel active pharmaceutical ingredients (APIs) and complex chiral molecules.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of peptide-mimetic drugs and other therapeutic agents.
• Asymmetric Synthesis: Used as a starting material or auxiliary in stereoselective reactions to construct complex molecules with high enantiomeric purity.
• Peptidomimetics & Prodrug Design: The (1S)-1,2-dimethylpropyl ester group can be utilized to modify peptide backbone properties or create prodrug formulations with tailored release profiles.
• Chemical Biology Research: Employed in the synthesis of labeled compounds, molecular probes, or modified amino acids for studying biological processes.
• Catalyst & Ligand Development: Serves as a precursor for creating novel chiral ligands or organocatalysts used in homogeneous catalysis.
• Fine Chemical Production: Integral to the multi-step synthesis of high-value specialty chemicals, agrochemicals, and advanced materials.
