Description

Bicyclo[2.2.1]Hept-5-Ene-2-Carboxaldehyde, 3-Acetyl-, (2-Endo,3-Exo)- (9Ci) is a high-purity, functionalized norbornene derivative that serves as a sophisticated chiral building block in advanced organic synthesis. Its rigid bicyclic framework and strategically positioned aldehyde and acetyl ketone functional groups make it an invaluable precursor for constructing complex molecular architectures with precise stereochemistry. This compound is essential for research and development chemists in the pharmaceutical and agrochemical industries, where it is used to develop novel active ingredients, chiral ligands, and specialty polymers.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of complex drug candidates, particularly in medicinal chemistry programs targeting central nervous system (CNS) and anti-inflammatory agents.
• Agrochemical Synthesis: Used in the development of advanced pesticides and herbicides, where its stereochemistry can influence biological activity and environmental selectivity.
• Chiral Ligand & Catalyst Development: Serves as a precursor for synthesizing novel chiral ligands and organocatalysts used in asymmetric synthesis.
• Specialty Polymer Monomer: Its norbornene core can be utilized in ring-opening metathesis polymerization (ROMP) to create polymers with unique thermal and mechanical properties for advanced materials.
• Fine Chemical & Flavor/Fragrance Intermediate: Employed in the multi-step synthesis of high-value fine chemicals and complex aroma molecules.
• Academic & Industrial R&D: A valuable tool for methodological development in organic synthesis and materials science research.

Quality Control

Every batch of Bicyclo[2.2.1]Hept-5-Ene-2-Carboxaldehyde, 3-Acetyl-, (2-Endo,3-Exo)- (9Ci) is manufactured under strict quality management protocols. Our products undergo rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and stereochemical integrity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity, identity, and impurity profiles. Our quality systems support development and production needs from laboratory to pilot scale.

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. This material is light-sensitive and easily oxidized; prolonged exposure to air or light should be avoided to maintain stability and purity.
