Description

Ethanone, 1-[2-(2-Propynyl)Cyclohexyl]-, cis- (9Ci) is a specialized organic compound featuring a cyclohexyl ring substituted with an ethanone (acetyl) group and a propargyl (2-propynyl) moiety in a cis-configuration. This unique structure makes it a valuable intermediate or building block in advanced organic synthesis, particularly for the development of complex molecules in pharmaceutical and agrochemical research. It is primarily sought by R&D chemists and process development scientists in fine chemical and life science industries for constructing novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the research and development of new drug candidates, especially those requiring a functionalized cyclohexane scaffold.
• Agrochemical Synthesis: Used in the creation of novel herbicides, fungicides, or insecticides where the propargyl group can be leveraged for further chemical transformations.
• Organic Synthesis Building Block: The acetyl and alkyne functionalities provide versatile handles for reactions like Sonogashira coupling, nucleophilic addition, and reduction, enabling the construction of complex molecular architectures.
• Material Science Research: Potential precursor for specialty polymers or ligands in catalytic systems, exploiting the rigidity of the cyclohexane ring and reactivity of the alkyne group.
• Flavor & Fragrance Industry: May be investigated as an intermediate for synthesizing novel aroma chemicals with specific stereochemical properties.
