Description

Bicyclo[2.2.1]Heptane-2-Carbonyl Chloride, 6-Ethylidene- (9Ci) is a specialized, high-value organic intermediate featuring a reactive acid chloride functional group on a strained norbornane-derived framework. This compound matters for its role as a key building block in the synthesis of complex molecules, enabling the introduction of the bicyclo[2.2.1]heptane scaffold, which is prized for imparting rigidity and unique three-dimensional geometry. It is primarily needed by research and development chemists in the pharmaceutical and agrochemical industries for creating novel active ingredients, as well as by material scientists developing advanced polymers and specialty chemicals.

Application

• Pharmaceutical Intermediate: A critical building block for synthesizing novel drug candidates, particularly those targeting central nervous system (CNS) disorders, where the rigid norbornane structure can influence bioavailability and receptor binding.
• Agrochemical Synthesis: Used in the research and development of new-generation pesticides and herbicides, where its unique structure contributes to the stability and efficacy of the active molecule.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of high-performance polymers with specific thermal and mechanical properties.
• Organic Synthesis Reagent: Employed in academic and industrial R&D labs for constructing complex, polycyclic organic compounds via reactions such as Friedel-Crafts acylation or nucleophilic substitution.
• Ligand and Catalyst Precursor: Utilized to create specialized chiral ligands or organometallic catalysts for asymmetric synthesis.
• Fine Chemical Production: Acts as an intermediate in the manufacture of flavors, fragrances, and other high-value specialty chemicals.

Quality Control

Our Bicyclo[2.2.1]Heptane-2-Carbonyl Chloride, 6-Ethylidene- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as an acid chloride, the container must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening and protected from moisture ingress. Keep away from strong bases, oxidizers, and sources of ignition.
