Description

(1S,5R)-1β,2-Dimethyl-2α-(4-Methylphenyl)Bicyclo[3.1.0]Hexane CAS NO 103439-82-3 is a high-purity, stereochemically defined bicyclic organic compound. This compound is valued for its unique three-dimensional structure, which makes it a critical chiral building block and advanced pharmaceutical intermediate in synthetic chemistry. It is primarily sought after by R&D and production teams in the pharmaceutical, agrochemical, and specialty chemical industries for the development of novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the synthesis of complex drug candidates, particularly those targeting central nervous system (CNS) disorders.
• Agrochemical Synthesis: Used in the research and development of new-generation pesticides and herbicides, where its rigid bicyclic core can impart specific biological activity.
• Ligand and Catalyst Development: Acts as a precursor for creating specialized ligands used in asymmetric catalysis to induce chirality in other molecules.
• Material Science Research: Investigated as a monomer or additive for creating polymers with unique thermal or mechanical properties due to its strained ring system.
• Fine Chemical Production: Employed in custom synthesis and contract manufacturing for producing high-value, low-volume specialty chemicals.
