Description

Cyclopentanone, 4-Ethyl-2-[3-(Trimethylsilyl)Propyl]-, (2R,4S)-Rel- (9Ci) is a high-purity, chiral organosilicon compound with the CAS number 507235-63-4, serving as a sophisticated synthetic building block in advanced organic chemistry. Its value lies in the precise stereochemistry and the functional silyl group, which are critical for constructing complex molecular architectures with high selectivity. This product is essential for researchers and process chemists in the pharmaceutical and agrochemical industries developing novel active ingredients, as well as in advanced materials science for creating specialty polymers and liquid crystals.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of novel active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) and antiviral drugs.
• Agrochemical Synthesis: Used in the production of advanced, stereospecific pesticides and herbicides where the specific spatial orientation of the molecule is crucial for bioactivity.
• Advanced Material Precursor: Serves as a monomer or functionalizing agent in the synthesis of specialty polymers, liquid crystals, and silicon-containing hybrid materials.
• Asymmetric Catalysis: Employed as a ligand precursor or a chiral auxiliary in catalytic systems designed for enantioselective synthesis.
• Organic Electronic Materials: Investigated for use in the development of organic light-emitting diodes (OLEDs) and semiconductors due to its silicon-functionalized, conjugated structure.
• Flavor & Fragrance Chemistry: Acts as an intermediate for synthesizing complex, high-value odorants and flavor compounds with specific stereochemical profiles.

Quality Control

Our Cyclopentanone, 4-Ethyl-2-[3-(Trimethylsilyl)Propyl]-, (2R,4S)-Rel- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC and GC, to ensure high chemical and enantiomeric purity suitable for demanding synthetic applications. Certificates of Analysis (COA) with detailed chromatographic data are provided with every shipment 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, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
