Description

(1R,2R)-2-Ethylcyclopropane-1-Carboxylic Acid CAS NO 1923743-63-8 is a high-purity, chiral cyclopropane derivative serving as a critical building block in advanced organic synthesis. Its value lies in its defined stereochemistry, which is essential for creating enantiomerically pure compounds with specific biological or material properties. This compound is primarily needed by research institutions and industrial R&D departments in the pharmaceutical, agrochemical, and specialty chemical sectors for developing novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of novel active pharmaceutical ingredients (APIs), particularly in antiviral, anticancer, and central nervous system (CNS) drug discovery programs.
• Agrochemical Synthesis: Used in the research and development of enantiomerically pure pesticides and herbicides, where specific stereochemistry can enhance efficacy and reduce environmental impact.
• Ligand and Catalyst Development: Serves as a precursor for chiral ligands and organocatalysts used in asymmetric synthesis to control stereoselectivity in chemical reactions.
• Material Science Research: Employed in the creation of specialty polymers and advanced materials where the rigid cyclopropane ring structure imparts unique physical properties.
• Flavor and Fragrance Chemistry: Potential intermediate for synthesizing complex, naturally occurring odorants and flavor compounds with specific stereocenters.
• Academic and Process Chemistry: A valuable reagent for methodological studies in organic chemistry and for scaling up synthetic routes in process development.
