Description

3-Buten-2-One, 4-Cyclobutyl- (9Ci) is a specialized organic building block featuring a reactive α,β-unsaturated ketone (enone) moiety fused with a strained cyclobutyl ring. This unique molecular architecture makes it a valuable intermediate for synthesizing complex, three-dimensional structures in advanced pharmaceutical and agrochemical research. It is primarily sought after by R&D chemists and process development scientists working on novel active ingredients, fragrances, and materials science.

Application

• Pharmaceutical Intermediate: Key synthon for constructing complex, strained-ring systems in drug discovery programs targeting CNS disorders, oncology, and anti-infectives.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides with unique modes of action.
• Fragrance & Flavor Chemistry: Serves as a precursor for synthesizing musky, amber, or woody odorants due to its cyclobutane backbone.
• Material Science Research: Building block for creating polymers and advanced organic materials with specific optical or electronic properties.
• Academic & Industrial R&D: A versatile reagent for methodology development in organic synthesis, particularly in cycloaddition and cross-coupling reactions.
