Description

5-Norbornen-2-Yl(Ethyl)Chlorodimethylsilane is a highly reactive organosilicon compound featuring a norbornene functional group. This unique structure makes it a valuable synthetic intermediate and cross-linking agent in advanced material science. It is primarily used by R&D and production teams in the silicone polymer, specialty chemical, and pharmaceutical intermediate sectors.

Application

• Silicone Polymer Modification: Key monomer for introducing reactive norbornene sites into silicone backbones for subsequent cross-linking via ring-opening metathesis polymerization (ROMP) or other addition reactions.
• Advanced Material Synthesis: Serves as a precursor for creating specialty silanes used in high-performance coatings, adhesives, and sealants with enhanced thermal and mechanical properties.
• Pharmaceutical Intermediates: Utilized in the synthesis of complex organic molecules and active pharmaceutical ingredients (APIs) where the norbornene moiety is incorporated for further functionalization.
• Surface Functionalization Agent: Used to modify inorganic surfaces (e.g., silica, metals) to impart specific chemical functionalities for composite materials and nanotechnology applications.
• Cross-linking Agent for Resins: Acts as a co-monomer or cross-linker in the production of thermosetting resins, improving their network density and performance characteristics.
• Research & Development: A valuable building block in academic and industrial R&D for exploring new polymeric architectures and organic synthesis pathways.

Quality Control

Our 5-Norbornen-2-Yl(Ethyl)Chlorodimethylsilane is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain purity. Keep away from strong bases and oxidizing agents.
