Description

Ethanone, 1-[2-(2-Propynyl)Cyclohexyl]-, trans- (9Ci) is a specialized organic compound featuring a cyclohexyl ring substituted with an ethanone (acetyl) group and a propynyl (propargyl) moiety in a trans configuration. This unique molecular architecture makes it a valuable advanced intermediate for the synthesis of complex molecules in pharmaceutical and agrochemical research. It is primarily sought by R&D chemists and process development scientists working on novel active ingredients, fragrances, and functional materials.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of potential drug candidates, particularly those requiring a rigid, functionalized cyclohexane scaffold.
• Agrochemical Research: Used in developing novel pesticides and herbicides, where the propynyl group can be leveraged for further chemical modifications.
• Fragrance & Flavor Chemistry: Acts as a precursor for musk-like or other complex odorant molecules due to its ketone and alkyne functionality.
• Material Science: Employed in the research of specialty polymers and advanced organic materials, where its structure can impart specific properties.
• Organic Synthesis: A versatile synthon for academic and industrial research, enabling reactions like Sonogashira coupling via the alkyne group or transformations of the ketone.
