Description

Cyclopentanol, 4-Ethyl-2-[3-(Trimethylsilyl)Propyl]-, (1R,2R,4S)-Rel- (9Ci) is a high-value, stereochemically defined organosilicon compound that serves as a critical chiral building block in advanced organic synthesis. Its unique structure, featuring both a cyclopentanol core and a trimethylsilylpropyl side chain, provides precise three-dimensional control for constructing complex molecular architectures. This intermediate is essential for research and development chemists in the pharmaceutical and agrochemical sectors, where it is used to create novel active ingredients with specific stereochemical requirements.

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 in the production of advanced, enantiomerically pure pesticides and herbicides where specific stereochemistry impacts biological activity.
• Advanced Material Precursor: Serves as a specialized monomer or modifier in the synthesis of silicon-containing polymers and specialty materials.
• Catalyst Ligand Development: Employed as a backbone for constructing novel chiral ligands used in asymmetric catalysis.
• Fine Chemical Production: Acts as a critical intermediate in multi-step syntheses of complex fragrance and flavor compounds.
• Academic & Industrial R&D: A valuable tool for methodological development in organic chemistry and process chemistry research.
