Description

5-Norbornene-2-Carbonyl Chloride is a highly reactive and versatile bicyclic acid chloride derivative, serving as a critical building block in advanced organic synthesis. Its strained norbornene framework and reactive acyl chloride group make it an essential precursor for constructing complex molecular architectures with tailored properties. This compound is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for applications ranging from catalyst development to the synthesis of novel monomers and functional materials.

Application

• Pharmaceutical Intermediate: A key synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring rigid, bicyclic scaffolds for enhanced biological activity.
• Polymer & Material Science: Serves as a functional monomer or cross-linking agent in the production of specialty polymers, including ring-opening metathesis polymerization (ROMP) resins and high-performance adhesives.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators that benefit from its unique structural motif.
• Ligand & Catalyst Development: Employed to create novel chiral or sterically hindered ligands for asymmetric catalysis and transition metal complexes.
• Organic Synthesis Reagent: Acts as a versatile acylating agent for introducing the norbornene-carbonyl moiety into target molecules under mild conditions.
• Research & Development: A valuable tool compound in academic and industrial R&D for exploring new chemical reactions and material properties.

Quality Control

Our 5-Norbornene-2-Carbonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, 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, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from strong bases, oxidizers, and sources of ignition.
