Description

Bicyclo[2.2.1]Hept-5-Ene-2-Carboxaldehyde, 3-(1-Methylethyl)-, (1S,2S,3S,4R)- (9Ci) is a high-purity, stereochemically defined chiral building block of significant interest in advanced organic synthesis. Its unique, rigid bicyclic framework and reactive aldehyde functionality make it a versatile precursor for constructing complex molecular architectures. This compound is primarily sought after by research institutions and pharmaceutical companies for applications in asymmetric catalysis, medicinal chemistry, and the development of novel fine chemicals.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of new active pharmaceutical ingredients (APIs), particularly for candidates requiring specific three-dimensional stereochemistry.
• Asymmetric Catalyst Ligand Synthesis: Used as a precursor for synthesizing novel chiral ligands and organocatalysts, which are critical for enantioselective transformations in fine chemical production.
• Advanced Material Research: Employed in the development of specialty polymers and functional materials where its rigid core structure can impart desired physical properties.
• Agrochemical Synthesis: Acts as a building block for creating novel, stereospecific crop protection agents and herbicides.
• Flavor and Fragrance Chemistry: Utilized in the synthesis of complex, naturally-derived odorants and flavor compounds due to its terpene-like structural features.
• Academic and R&D Laboratories: A valuable reagent for methodological studies in organic synthesis, including cycloaddition reactions and stereochemical investigations.

Quality Control

Our Bicyclo[2.2.1]Hept-5-Ene-2-Carboxaldehyde, 3-(1-Methylethyl)-, (1S,2S,3S,4R)- (9Ci) is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high chemical purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques to verify identity, enantiomeric excess, and impurity profiles. Certificates of Analysis (COA) detailing specific results for chiral purity, chemical assay, and related substances are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, the container should be kept sealed after each use to minimize exposure to air.
