Description

Ethanone, 1-[(4Ar,8As)-3,4,4A,5,6,7,8,8A-Octahydro-8A-Hydroxy-4A-Methyl-1-Naphthalenyl]-, Rel- (9Ci) is a high-purity, stereochemically defined ketone derivative of a decalin system, serving as a critical chiral building block and advanced intermediate in complex organic synthesis. Its rigid, fused-ring structure with defined stereocenters makes it invaluable for constructing intricate molecular architectures with high precision. This compound is primarily sought by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs), agrochemicals, and specialty fine chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of novel therapeutic agents, particularly in steroid-mimetic or complex polycyclic drug candidates.
• Agrochemical Synthesis: Used in the production of advanced, high-specificity pesticides and herbicides where stereochemistry impacts biological activity.
• Asymmetric Catalysis & Ligand Development: Serves as a precursor for developing novel chiral ligands and catalysts used in enantioselective synthesis.
• Fine Chemical & Flavor/Fragrance Intermediate: Employed in the synthesis of complex, high-value odorants and flavoring agents with specific stereochemical profiles.
• Academic & Industrial R&D: A valuable tool for methodological studies in organic chemistry, including novel cyclization and functionalization reactions.
• Material Science Precursor: Potential use in synthesizing specialized polymers or liquid crystals with tailored properties derived from its rigid backbone.
