Description

Cyclobutanone, 2-(Cyclopropylethynyl)- (9Ci) is a specialized organic building block featuring a cyclobutanone core functionalized with a cyclopropylethynyl substituent. This unique molecular architecture makes it a valuable intermediate for advanced synthetic chemistry, particularly in the construction of complex, strained-ring systems. It is primarily utilized by research chemists and process development scientists in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the research and development of new drug candidates, especially those requiring strained carbocyclic frameworks.
• Agrochemical Synthesis: Used in the creation of novel herbicides, fungicides, and insecticides where the cyclopropane and cyclobutane motifs can impart unique biological activity.
• Material Science Research: Acts as a precursor for developing advanced polymers or organic electronic materials with specific structural properties.
• Academic & R&D Laboratories: Employed in methodological studies and the synthesis of complex natural product analogs or novel chemical entities.
• Fine Chemical Production: Utilized in custom synthesis and contract manufacturing for producing high-value, low-volume specialty chemicals.
