Description

2-Pentanone, 3-Nitro-, (3S)- (9Ci) is a chiral, nitro-functionalized ketone, a high-value intermediate in fine chemical synthesis. Its defined stereochemistry and reactive functional groups make it a critical building block for the production of complex, optically active molecules. This compound is essential for research and development chemists and process engineers in the pharmaceutical and agrochemical industries seeking to introduce specific chiral centers and nitro groups into target molecules.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the asymmetric synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring a specific (S)-configuration.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, insecticides, and fungicides where the nitro-ketone moiety is a crucial structural element.
• Ligand and Catalyst Development: Acts as a precursor for the synthesis of chiral ligands and organocatalysts used in enantioselective transformations.
• Fine Chemical Production: Employed in the multistep synthesis of specialty chemicals, flavors, and fragrances requiring high stereochemical purity.
• Academic and Industrial R&D: A valuable tool for methodological development in organic chemistry, exploring new nitro-aldol and related condensation reactions.
