Description

Cyclopentanone, 3-Acetyl-, (R)- (9Ci) is a chiral, high-purity chemical intermediate characterized by its ketone and acetyl functional groups on a cyclopentane ring. This compound matters for its role as a sophisticated building block in the synthesis of complex, optically active molecules, where its defined stereochemistry is critical for biological activity and material properties. It is primarily needed by research and development teams in the pharmaceutical, agrochemical, and advanced materials sectors for creating novel active ingredients and specialty chemicals. The product is supplied under stringent quality control to ensure batch-to-batch consistency for demanding synthetic applications.

Application

• Pharmaceutical Intermediate: Serves as a key chiral precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) and anti-inflammatory drugs.
• Agrochemical Synthesis: Used in the research and production of advanced, stereospecific herbicides, fungicides, and plant growth regulators.
• Fine Chemical Building Block: Employed in organic synthesis for constructing complex natural products, flavors, and fragrances requiring specific optical purity.
• Material Science Research: Acts as a monomer or modifying agent in the development of specialized polymers and liquid crystals with tailored optical properties.
• Asymmetric Catalysis: Utilized as a substrate or ligand precursor in the development and study of new asymmetric catalytic reactions.

Quality Control

Our Cyclopentanone, 3-Acetyl-, (R)- (9Ci) is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, identity confirmation by IR and NMR, and quantification of key impurities. Certificates of Analysis (COA) documenting all critical parameters are provided to ensure full traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at a controlled room temperature (15-25°C). Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and potential concentration changes. Keep away from heat, sparks, and open flames.
