Description

5-Oxazolidinecarboxylicacid,2-Oxo-,Methylester,(5S)-(9Ci) is a high-value, chiral oxazolidinone derivative used as a critical synthetic intermediate. This compound is essential for the stereoselective construction of complex molecules, particularly in pharmaceutical research and development. It is primarily sought after by fine chemical manufacturers and R&D laboratories in the pharmaceutical and agrochemical sectors for the synthesis of active pharmaceutical ingredients (APIs) and other biologically active compounds.

Application

• Pharmaceutical Intermediate: A key chiral building block for the synthesis of novel antibiotics, antiviral agents, and other therapeutic molecules.
• Asymmetric Synthesis: Employed as an auxiliary or reagent in stereoselective organic reactions to induce chirality in target molecules.
• Agrochemical Research: Used in the development of new, enantiomerically pure pesticides and herbicides.
• Academic & Industrial R&D: Serves as a valuable starting material for methodological studies in organic chemistry and medicinal chemistry programs.
• Peptidomimetics: Utilized in the design and synthesis of peptide analogs and conformationally restricted scaffolds.
