Description

Butanoic Acid, 4-[(Methoxycarbonyl)Amino]-2-Methyl-, Methyl Ester, (+)- is a chiral, non-racemic ester derivative of butanoic acid featuring a carbamate-protected amino group. This compound matters as a high-value pharmaceutical intermediate and chiral building block for the synthesis of complex bioactive molecules, offering precise stereochemical control. It is primarily needed by R&D chemists and process development teams in the pharmaceutical and fine chemical industries for creating novel active pharmaceutical ingredients (APIs) and agrochemicals.

Application

• Pharmaceutical Intermediate: Key chiral synthon in the asymmetric synthesis of potential drug candidates and active pharmaceutical ingredients (APIs).
• Agrochemical Research: Building block for developing novel, stereospecific herbicides, fungicides, and insecticides.
• Peptidomimetics & Prodrug Design: Utilized in the construction of peptide analogs and prodrug molecules due to its protected amino acid ester structure.
• Asymmetric Catalysis & Ligand Synthesis: Serves as a precursor for chiral ligands and auxiliaries used in enantioselective transformations.
• Fine Chemical Synthesis: Intermediate for specialty chemicals requiring high enantiomeric purity in flavors, fragrances, and advanced materials.
• Academic & Industrial R&D: Valuable reference standard and starting material for methodological development in organic and medicinal chemistry.
