Description

Methyl (2E)-3-Cyclopentylprop-2-Enoate is a high-purity, unsaturated ester building block with significant utility in advanced organic synthesis. Its unique structure, featuring a cyclopentyl group conjugated to an acrylate moiety, makes it a valuable intermediate for constructing complex molecular architectures. This compound is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and specialty fragrance industries seeking to introduce specific steric and electronic properties into target molecules.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring cyclopentane-based scaffolds.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators where the cyclopentyl group modulates biological activity and environmental persistence.
• Flavor & Fragrance Ingredient: Acts as a precursor for musk analogs and other specialty aroma chemicals, contributing woody and amber notes.
• Material Science Monomer: Investigated as a co-monomer for creating specialty polymers with tailored properties like flexibility, hydrophobicity, or specific refractive indices.
• Organic Synthesis Building Block: Employed in Michael additions, Diels-Alder reactions, and catalytic hydrogenations to create more complex, functionalized molecules for research.
• Ligand & Catalyst Development: Utilized in the preparation of novel chiral ligands for asymmetric catalysis, leveraging the steric bulk of the cyclopentyl ring.
