Description

Cyclopentanone, 2-Ethyl-4-[3-(Trimethylsilyl)Propyl]-, (2R,4S)-Rel- (9Ci) is a high-purity, chiral organosilicon derivative of cyclopentanone, serving as a sophisticated building block in advanced organic synthesis. Its defined stereochemistry and functional groups make it a critical intermediate for constructing complex molecular architectures with high enantiomeric purity. This compound is essential for R&D and production in the pharmaceutical and fine chemical industries, where precise control over molecular structure is paramount.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring specific stereocenters.
• Asymmetric Catalysis: Used as a ligand precursor or a chiral auxiliary in catalytic systems to induce enantioselectivity in chemical reactions.
• Advanced Material Synthesis: Serves as a monomer or functional modifier in the development of specialty polymers and silicon-containing advanced materials.
• Agrochemical Research: Employed in the research and development of novel, stereochemically-defined pesticides and herbicides.
• Flavor & Fragrance Chemistry: Acts as a precursor for synthesizing complex, high-value odorants and flavoring agents with specific olfactory profiles.
• Academic & Industrial R&D: A valuable tool for methodological development in organic synthesis and medicinal chemistry research programs.

Quality Control

Our production of Cyclopentanone, 2-Ethyl-4-[3-(Trimethylsilyl)Propyl]-, (2R,4S)-Rel- (9Ci) adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical characterization, including chiral purity analysis (HPLC/GC), to ensure consistent enantiomeric excess and chemical identity. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided to guarantee traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
