Description

Bicyclo[2.2.1]Hept-5-Ene-2-Carboxaldehyde, 2,3-Dimethyl-, (1R,2R,3R,4S)-Rel- (9Ci) is a high-purity, stereochemically defined chiral building block of significant interest in advanced organic synthesis. Its rigid bicyclic framework and aldehyde functionality make it a versatile precursor for constructing complex molecular architectures with precise three-dimensional control. This compound is primarily sought after by pharmaceutical R&D and fine chemical sectors for applications in asymmetric catalysis and the development of novel active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of novel therapeutic agents, particularly for central nervous system (CNS) and anti-inflammatory targets.
• Asymmetric Catalysis: Serves as a sophisticated ligand precursor or a chiral scaffold in the design of catalysts for enantioselective synthesis.
• Advanced Material Research: Used in the synthesis of specialty polymers and liquid crystals where the rigid, chiral structure imparts specific optical or mechanical properties.
• Agrochemical Synthesis: Employed in the development of new, stereospecific pesticides and herbicides with enhanced efficacy and environmental profiles.
• Flavor & Fragrance Chemistry: Acts as a starting material for creating complex, naturally-derived odorants and flavoring agents with high stereochemical purity.
• Academic & Industrial R&D: A valuable tool for methodological studies in organic chemistry, including cycloaddition reactions and stereochemical investigations.

Quality Control

Every batch of our chiral aldehydes is produced and tested under strict quality management protocols to ensure exceptional purity and stereochemical integrity. Our products undergo rigorous analytical testing, including chiral HPLC, GC, and NMR, to confirm identity, enantiomeric/excess, and impurity profiles. Certificates of Analysis (COA) detailing all specifications are provided with each shipment and are available upon request.

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, the container should be kept tightly sealed when not in use to minimize exposure to air and moisture.
