Description

Bicyclo[2.2.1]Heptane-2-Carbonyl Chloride, 5-Ethylidene- (9Ci) is a specialized, high-purity organic intermediate featuring a reactive acid chloride functional group on a norbornane-derived scaffold. This compound is valued for its role as a key building block in advanced organic synthesis, enabling the introduction of the bicyclo[2.2.1]heptane moiety into target molecules. It is primarily sought by research and development chemists in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and complex molecular architectures.

Application

• Pharmaceutical Intermediate: A critical building block for synthesizing novel drug candidates, particularly those targeting the central nervous system (CNS) or requiring rigid, three-dimensional structures.
• Agrochemical Synthesis: Used in the research and development of new pesticides and herbicides, where the norbornane structure can impart specific biological activity and stability.
• Advanced Material Precursor: Serves as a monomer or cross-linking agent in the development of specialty polymers with unique thermal or mechanical properties.
• Organic Synthesis Reagent: Employed in academic and industrial R&D labs for constructing complex, polycyclic organic molecules via reactions such as Friedel-Crafts acylation or amide bond formation.
• Ligand and Catalyst Development: Utilized to create novel chiral ligands or organocatalysts for asymmetric synthesis applications.
• Fine Chemical Production: Acts as a key intermediate in the multi-step synthesis of flavors, fragrances, and other high-value specialty chemicals.

Quality Control

Our Bicyclo[2.2.1]Heptane-2-Carbonyl Chloride, 5-Ethylidene- (9Ci) is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity, suitable for demanding synthetic applications. Each lot is analyzed using advanced chromatographic and spectroscopic techniques (HPLC, GC, NMR). A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

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