Description

Cyclopropanecarboxylic Acid, 1,2-Dimethyl-, Methyl Ester, (1R,2R)-Rel- (9Ci) CAS NO 104131-70-6 is a high-purity, stereochemically defined chiral building block essential for advanced organic synthesis. Its value lies in the rigid, strained cyclopropane ring system, which is a key structural motif for modulating the biological activity and physical properties of target molecules. This compound is critically needed by pharmaceutical and agrochemical R&D teams for the development of novel active ingredients, including potential drugs and crop protection agents.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) and antiviral drug candidates.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, where the cyclopropane moiety can enhance stability and efficacy.
• Ligand and Catalyst Development: Acts as a precursor for chiral ligands and organocatalysts used in asymmetric synthesis to create enantiomerically pure compounds.
• Material Science Research: Employed in the development of specialty polymers and liquid crystals, where its rigid structure can influence material properties.
• Flavor and Fragrance Chemistry: Utilized as an intermediate for synthesizing complex aroma chemicals with unique olfactory profiles.
• Academic and R&D Laboratories: A valuable reagent for methodological studies in organic chemistry and the exploration of new cyclopropanation reactions.
