Description

Bicyclo[2.2.1]Hept-5-Ene-2-Carboxylic Acid, 2-Cyanoethyl Ester (9Ci) is a specialized bicyclic organic compound featuring a norbornene core functionalized with a carboxylic acid ester group containing a cyanoethyl moiety. This unique structure makes it a valuable high-purity chemical intermediate for advanced synthesis, particularly in the development of polymers, pharmaceuticals, and fine chemicals. It is primarily sought by R&D chemists and process development scientists in industries focused on creating novel materials with specific thermal or mechanical properties, as well as in medicinal chemistry for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs), especially for compounds requiring a rigid, functionalized bicyclic framework.
• Advanced Polymer Synthesis: Used as a monomer or co-monomer in ring-opening metathesis polymerization (ROMP) to produce specialty polymers with tailored properties for high-performance applications.
• Fine Chemical Production: Acts as a precursor in the multi-step synthesis of complex organic molecules, agrochemicals, and dyes, leveraging its reactive ester and alkene functionalities.
• Material Science Research: Employed in R&D for developing new polymeric materials, coatings, or resins with enhanced stability, adhesion, or optical characteristics.
• Cross-linking Agent: Potential use in creating cross-linked polymer networks due to the presence of the polymerizable norbornene double bond.
• Ligand and Catalyst Development: Can be utilized to synthesize novel ligands or organometallic complexes for catalytic applications.
