Description

Bicyclo[2.2.1]Hept-2-Ene-7-Carbonyl Chloride, Syn- (9Ci) is a highly reactive and versatile bicyclic acid chloride derivative, serving as a critical chiral building block in advanced organic synthesis. Its value lies in its rigid norbornene skeleton and the reactive carbonyl chloride group, enabling precise stereoselective transformations. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries developing novel active ingredients, as well as in materials science for creating specialized polymers and ligands.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of complex drug candidates, particularly those requiring the norbornene framework for biological activity or as a conformational constraint.
• Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides where its specific stereochemistry contributes to efficacy and selectivity.
• Polymer Science: Monomer or cross-linking agent for the synthesis of specialty polymers with unique thermal and mechanical properties, such as polyimides or addition polymers.
• Catalyst & Ligand Development: Precursor for creating novel chiral ligands and organometallic catalysts used in asymmetric synthesis.
• Fine Chemical Production: Building block for synthesizing complex fragrances, flavors, and other high-value specialty chemicals.
• Academic & R&D: A valuable reagent for methodological studies in organic chemistry, particularly in cycloaddition and ring-opening reactions.

Quality Control

Our Bicyclo[2.2.1]Hept-2-Ene-7-Carbonyl Chloride, Syn- (9Ci) is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral integrity, NMR for structural confirmation, and titration for assay. We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring traceability and compliance with your research or production specifications. Our commitment is to deliver material of consistent high purity and reliable stereochemical purity.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and moisture-sensitive nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong bases and oxidizing agents.
