Description

Cyclobutanone, 2-(Butylthio)-3-Ethoxy-2-Methyl-, trans- (9Ci) is a specialized organic compound featuring a unique cyclobutanone core substituted with thioether and ethoxy functional groups. This molecular architecture 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 scientists working on novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel drug candidates, particularly those requiring a functionalized cyclobutanone scaffold.
• Agrochemical Research: Used in the development of new herbicides, fungicides, or insecticides where its specific stereochemistry and substituents are critical for bioactivity.
• Organic Synthesis Reagent: Serves as a versatile precursor for cycloaddition reactions, ring-opening transformations, and the introduction of sulfur-containing motifs.
• Material Science Research: Potential intermediate for creating specialized monomers or ligands used in polymer and catalyst development.
• Academic & Industrial R&D: Employed in methodological studies and the exploration of new chemical spaces in discovery chemistry programs.
