Description

cis-(±)-2,2-Dimethyl-3-(2-Methylprop-1-Enyl)Cyclopropanecarboxylic Acid CAS NO 2935-23-1 is a high-purity cyclopropanecarboxylic acid derivative characterized by its specific cis-isomer configuration and the presence of a prenyl (2-methylprop-1-enyl) substituent. This compound serves as a critical chiral building block and synthetic intermediate in advanced organic synthesis, valued for its unique sterically constrained three-membered ring structure. It is essential for research and development chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce cyclopropane motifs into target molecules.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring chiral, sterically hindered carboxylic acid components.
• Agrochemical Synthesis: Building block for developing novel pesticides, herbicides, and fungicides where the cyclopropane ring enhances biological activity and stability.
• Ligand and Catalyst Development: Used in the preparation of chiral ligands for asymmetric catalysis and organometallic complexes.
• Fragrance and Flavor Chemistry: Intermediate for synthesizing specific aroma chemicals that benefit from the structural characteristics of the cyclopropane ring.
• Material Science Research: Monomer or modifier in the development of specialized polymers with tailored properties.
• Academic and R&D Laboratories: A valuable reagent for methodological studies in organic chemistry, including ring-opening and functionalization reactions.
