Description

Ethanone,1-(2-Ethynylcyclohexyl)- (CAS NO 155222-56-3) is a specialized organic building block featuring a unique cyclohexyl ring substituted with both an ethynyl and an acetyl (ethanone) group. This molecular architecture makes it a valuable intermediate for synthesizing complex molecules in advanced research and development. It is primarily sought after by pharmaceutical, agrochemical, and advanced material scientists for constructing novel chemical entities.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the research and development of new active pharmaceutical ingredients (APIs), particularly for creating complex ring systems.
• Agrochemical Research: Used in the synthesis of novel herbicides, fungicides, and insecticides, leveraging its reactive ethynyl moiety for molecular diversification.
• Material Science: Acts as a precursor for specialty polymers, liquid crystals, or organic electronic materials due to its rigid cyclohexyl backbone and functional groups.
• Organic Synthesis: A versatile building block in academic and industrial R&D for constructing complex natural product analogs and other fine chemicals.
• Cross-Coupling Reactions: The ethynyl group makes it a suitable substrate for Sonogashira and other palladium-catalyzed coupling reactions.
