Description

3-Buten-2-One, 4-(1-Methylcyclobutyl)-, (E)- (9Ci) is a specialized organic intermediate featuring a unique α,β-unsaturated ketone (enone) structure with a methylcyclobutyl substituent. This molecular architecture makes it a valuable building block for synthesizing complex molecules, particularly in the pharmaceutical and agrochemical sectors. It is primarily sought by R&D chemists and process development scientists for constructing novel chemical entities and advanced materials.

Application

• Pharmaceutical Intermediate: A key synthon for the synthesis of active pharmaceutical ingredients (APIs), especially those requiring a sterically defined, functionalized cyclobutane ring system.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides, leveraging its reactive enone moiety for further chemical transformations.
• Flavor & Fragrance Chemistry: Serves as a precursor for creating unique musk-like or woody aroma compounds due to its methylcyclobutyl group.
• Material Science Research: Employed in the development of specialty polymers and advanced organic materials where its rigid structure can influence material properties.
• Organic Synthesis Building Block: Utilized in academic and industrial R&D for cycloaddition reactions, conjugate additions, and other carbon-carbon bond-forming processes.
