Description

Cyclohexanone, 3-Ethyl-3,5-Dihydroxy-2,4,6-Trimethyl-, (2S,3S,4S,5S,6S)- (9Ci) is a high-purity, stereochemically defined derivative of cyclohexanone, valued for its specific chiral configuration and functional groups. This compound is a critical advanced intermediate in fine chemical synthesis, particularly for the development of complex, optically active molecules. It is primarily sought by research and development teams in the pharmaceutical and agrochemical industries for use in asymmetric synthesis and the creation of novel active ingredients.

Application

• Pharmaceutical Intermediate: A key chiral building block for the synthesis of complex drug candidates, especially those requiring specific stereochemistry for biological activity.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides where its structural motifs contribute to target specificity.
• Fine Chemical Production: Serves as a precursor in the manufacture of specialty chemicals, flavors, and fragrances requiring high enantiomeric purity.
• Asymmetric Catalysis Research: Employed as a substrate or ligand precursor in academic and industrial research focused on developing new catalytic methodologies.
• Material Science: Potential monomer or cross-linking agent in the development of specialized polymers with unique optical or mechanical properties.

Quality Control

Our Cyclohexanone, 3-Ethyl-3,5-Dihydroxy-2,4,6-Trimethyl-, (2S,3S,4S,5S,6S)- (9Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and stereochemical integrity. Certificates of Analysis (COA) detailing specifications such as chiral purity (enantiomeric excess), chemical purity (by HPLC), and residual solvents are provided and available upon request to support your regulatory and R&D needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider the use of desiccants.
