Description

Bicyclo[4.2.1]Non-1(8)-Ene CAS NO 23057-35-4 is a strained, bicyclic hydrocarbon featuring a unique bridged structure with a double bond, making it a valuable and versatile intermediate in advanced organic synthesis. Its rigid, three-dimensional framework is crucial for constructing complex molecular architectures, particularly in pharmaceutical and material science research. This compound is primarily sought by R&D chemists and process development scientists working on novel active pharmaceutical ingredients (APIs), specialty polymers, and high-performance materials where precise stereochemistry and structural complexity are required.

Application

• Pharmaceutical Intermediate: Serves as a key building block for synthesizing novel drug candidates, especially those requiring complex, strained-ring systems to modulate biological activity.
• Material Science Research: Used in the development of specialty polymers and advanced organic materials with tailored thermal or mechanical properties.
• Organic Synthesis Reagent: Acts as a dienophile or strained alkene component in cycloaddition reactions (e.g., Diels-Alder) to create polycyclic compounds.
• Catalysis & Ligand Development: Employed as a precursor for synthesizing novel ligands and organometallic catalysts in asymmetric synthesis.
• Fragrance & Flavor Chemistry: Potential intermediate for creating unique, musky, or woody odorants due to its complex bicyclic structure.
• Academic & Industrial R&D: A critical tool for methodological studies and exploring new chemical spaces in synthetic organic chemistry.

Quality Control

Every batch of Bicyclo[4.2.1]Non-1(8)-Ene is produced and analyzed under strict quality management protocols. We provide comprehensive analytical data to ensure identity, purity, and consistency for your critical research and development projects. A Certificate of Analysis (COA) detailing specifications such as assay (by GC), identity (by FT-IR and/or NMR), and impurity profile is available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at room temperature (15-25°C). Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and potential concentration changes. Keep away from heat, sparks, and open flames.
