Description

Ethanone, 1-[(1R,2R)-2-Ethylcyclohexyl]- (9Ci) is a chiral, substituted cyclohexyl ketone of significant interest in advanced organic synthesis. This compound matters as a high-value, stereochemically defined building block for creating complex molecules with specific three-dimensional architectures. It is primarily needed by research chemists and process development scientists in the pharmaceutical and agrochemical industries for applications such as chiral ligand synthesis, fragrance intermediate development, and the construction of novel active pharmaceutical ingredients (APIs).

Application

• Chiral Intermediate in Pharmaceutical Synthesis: Serves as a key precursor for the development of enantiomerically pure drugs, particularly in central nervous system (CNS) and anti-inflammatory research.
• Agrochemical Active Ingredient Development: Used in the synthesis of novel, stereoselective herbicides, fungicides, and plant growth regulators.
• Fragrance and Flavor Chemistry: Acts as a building block for synthetic musk compounds and other complex odorants due to its substituted cyclohexane structure.
• Catalyst and Ligand Preparation: Utilized in the design and synthesis of novel chiral catalysts for asymmetric hydrogenation and other stereoselective transformations.
• Advanced Material Research: Investigated as a monomer or modifier in the synthesis of specialty polymers with unique optical or mechanical properties.
• Organic Synthesis Reference Standard: Employed as a high-purity analytical standard for method development and quality control in chiral analysis.
