Description

(S)-3-Phenylcyclopentanone is a high-purity chiral building block and key intermediate in organic synthesis. Its defined stereochemistry is critical for producing enantiomerically pure compounds, offering significant value in the development of advanced materials and active pharmaceutical ingredients (APIs). This product is essential for research and manufacturing in the pharmaceutical, agrochemical, and specialty chemical industries, where precise molecular architecture dictates efficacy and performance.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of novel drug candidates, particularly in central nervous system (CNS) and cardiovascular therapeutic areas.
• Agrochemical Synthesis: Used in the production of enantiomerically pure pesticides and herbicides, where the specific (S)-enantiomer can provide enhanced biological activity.
• Asymmetric Catalyst Ligand Precursor: Serves as a starting material for the development of chiral ligands used in asymmetric hydrogenation and other catalytic transformations.
• Flavor and Fragrance Chemistry: Employed in the synthesis of complex odorants and flavoring agents that require specific stereochemical profiles.
• Material Science Research: Acts as a monomer or building block for advanced polymers and liquid crystals with specific optical properties.
• Academic and R&D Laboratories: A valuable reagent for methodological development in organic chemistry and stereoselective synthesis studies.

Quality Control

Our (S)-3-Phenylcyclopentanone is manufactured under strict quality management systems to ensure batch-to-batch consistency and high enantiomeric purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as chiral purity (enantiomeric excess), chemical purity, and identity confirmation. We support compliance with cGMP, ISO, and other relevant quality standards for pharmaceutical and fine chemical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under dry conditions to prevent degradation. Keep away from heat and incompatible materials.
