Description

Bicyclo[2.2.1]Heptane-2-Carboxaldehyde, 7,7-Dimethyl-, (1S,2S,4R)- (9Ci) is a high-purity, stereochemically defined chiral building block of significant interest in advanced organic synthesis. Its rigid, functionalized norbornane skeleton makes it a valuable precursor for constructing complex molecular architectures with precise three-dimensional control. This compound is primarily sought after by research and development teams in the pharmaceutical and agrochemical sectors for the synthesis of novel active ingredients, chiral ligands, and specialty materials.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of novel active pharmaceutical ingredients (APIs), particularly those requiring a rigid, functionalized core structure.
• Agrochemical Synthesis: Used in the creation of advanced, stereospecific pesticides and herbicides where the defined spatial orientation of the molecule is critical for bioactivity.
• Chiral Ligand & Catalyst Development: Serves as a foundational scaffold for designing new asymmetric catalysts and auxiliaries used in enantioselective transformations.
• Flavor & Fragrance Chemistry: Employed in the synthesis of high-value, complex odorants and flavoring agents that benefit from its unique bicyclic framework.
• Material Science Research: Acts as a monomer or cross-linking agent in the development of specialized polymers with tailored thermal and mechanical properties.
• Academic & Industrial R&D: A versatile tool for methodological studies in organic chemistry, including cycloaddition reactions and stereochemical investigations.
