Description

Ethanone, 1-[(2R,3S)-Tetrahydro-2-Methyl-3-Furanyl]-, Rel- (9Ci) is a high-purity chiral intermediate of significant importance in advanced organic synthesis. This compound matters because it provides a critical, stereochemically defined building block for the development of complex molecules, enabling precise control over the three-dimensional architecture of target compounds. It is primarily needed by research and development teams in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients, as well as by fine chemical manufacturers producing specialty flavors and fragrances.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of new drug candidates, particularly in antiviral, antibacterial, and central nervous system (CNS) therapeutic areas.
• Agrochemical Synthesis: Used in the production of advanced, stereoselective pesticides and herbicides where specific chirality is crucial for biological activity.
• Flavor & Fragrance (F&F) Industry: Serves as a precursor for synthesizing specific, high-value aroma chemicals with desired olfactory profiles.
• Academic & Contract Research: Employed in university and CRO laboratories for methodological studies in asymmetric synthesis and catalysis.
• Fine Chemical Production: Acts as a building block for other specialty chemicals requiring the tetrahydrofuran moiety with defined stereochemistry.
