Description

(1β,4β)-5β,6α-Bis(Diphenylphosphinyl)Bicyclo[2.2.1]Hepta-2-Ene is a specialized organophosphorus compound featuring a rigid norbornene backbone, making it a valuable chiral ligand and building block in advanced synthesis. Its core value lies in its ability to induce high stereoselectivity in transition metal-catalyzed reactions, which is critical for producing enantiomerically pure intermediates. This product is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries who require precise control over molecular architecture for developing new active ingredients and functional materials.

Application

• As a chiral ligand in asymmetric hydrogenation, hydroformylation, and cross-coupling reactions.
• Key intermediate in the synthesis of pharmaceuticals and bioactive molecules requiring specific stereochemistry.
• Building block for developing novel organocatalysts and metal-organic frameworks (MOFs).
• Use in agrochemical research for creating enantiomerically pure pesticides and herbicides.
• Precursor for specialty polymers and materials with tailored electronic or optical properties.
• Catalyst component in fine chemical and fragrance manufacturing processes.

Quality Control

Our (1β,4β)-5β,6α-Bis(Diphenylphosphinyl)Bicyclo[2.2.1]Hepta-2-Ene is produced and tested under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay, chiral purity, and impurity profiles are available upon request 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 place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
