Description

Bicyclo[2.2.1]Heptan-2-One, 1-Ethyl-, Oxime, (1S,4R)- (9Ci) is a high-purity, stereochemically defined oxime derivative of a substituted norbornane (bicyclo[2.2.1]heptane) framework. This compound is a valuable chiral building block and intermediate in advanced organic synthesis, prized for its rigid, three-dimensional structure which can impart unique steric and electronic properties to target molecules. It is primarily sought by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for applications in asymmetric synthesis, medicinal chemistry, and the development of performance materials. CAS number 802917-50-6.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of novel active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) and anti-inflammatory targets.
• Asymmetric Catalysis Ligand Precursor: Used in the synthesis of chiral ligands for transition metal catalysis, enabling enantioselective transformations critical for producing single-isomer compounds.
• Agrochemical Synthesis: Acts as a building block for developing new generation pesticides and herbicides with enhanced efficacy and selectivity.
• Fine Chemical & Specialty Material Production: Employed in the creation of advanced polymers, liquid crystals, or organic electronic materials where the norbornane scaffold provides thermal stability and rigidity.
• Academic & Industrial Research: Utilized in methodological studies and exploration of new synthetic routes involving oxime chemistry and strained ring systems.
• Flavor & Fragrance Intermediate: Potential use in the synthesis of complex odorants and flavoring agents that require specific stereochemistry.
