Description

Ethanone, 1-(3-Ethynylcyclobutyl)-, cis- (9Ci) is a specialized organic compound featuring a cyclobutyl ring substituted with an ethynyl group and an acetyl (ethanone) moiety. This unique structure 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 teams working on novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of potential drug candidates, particularly those requiring a rigid, three-dimensional cyclobutane scaffold.
• Agrochemical Research: Used in the development of new herbicides, fungicides, or insecticides where the acetylene and ketone functionalities allow for further chemical modifications.
• Material Science Precursor: Acts as a monomer or cross-linking agent in the development of specialty polymers with tailored thermal or mechanical properties.
• Ligand Synthesis: Utilized in organometallic chemistry for creating novel ligands used in catalysis.
• Chemical Biology Probes: Employed in the design of molecular probes for studying biological processes due to its reactive functional groups.
