Description

2-Pentanone, 4-Methoxy-, (4R)- (9Ci) is a chiral, non-racemic ketone derivative with a specific stereochemical configuration at the 4-position. This compound matters as a valuable chiral building block and intermediate in the synthesis of complex organic molecules, where its defined stereochemistry is critical for producing enantiomerically pure products. It is needed by research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries for applications in asymmetric synthesis and the development of active ingredients.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of enantiomerically pure active pharmaceutical ingredients (APIs).
• Asymmetric Synthesis: Used as a starting material or auxiliary in catalytic asymmetric reactions to construct complex molecular architectures.
• Agrochemical Research: Serves as a building block for the synthesis of novel, stereospecific pesticides and herbicides.
• Ligand and Catalyst Development: Utilized in the preparation of chiral ligands for metal-catalyzed transformations.
• Fine Chemical Production: Employed in the multistep synthesis of specialty chemicals and advanced materials where optical purity is essential.
• Academic and R&D Laboratories: A valuable reagent for methodological studies in organic chemistry and stereochemistry.
