Description

Cyclopentanone, 3-Ethyl-4-Propyl-, (3S,4S)- (9Ci) is a high-purity, chiral cyclopentanone derivative characterized by its specific stereochemistry at the 3 and 4 positions. This compound serves as a critical chiral building block and advanced intermediate in the synthesis of complex organic molecules, where its defined stereocenter is essential for imparting specific biological or physical properties. It is primarily utilized by research institutions and industrial R&D departments in the pharmaceutical, agrochemical, and specialty chemical sectors for developing novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of novel active pharmaceutical ingredients (APIs), particularly in stereoselective synthesis.
• Agrochemical Synthesis: Used as a building block in the production of advanced, enantiomerically pure pesticides and herbicides.
• Ligand and Catalyst Development: Serves as a precursor for chiral ligands and organocatalysts used in asymmetric synthesis.
• Fragrance and Flavor Chemistry: Potential intermediate for creating specific, complex odorant molecules due to its ketone functionality and alkyl side chains.
• Material Science Research: Investigated as a monomer or modifying agent for specialized polymers with tailored properties.
• Academic and Industrial R&D: A valuable reagent for methodological studies in organic chemistry and process development.
