Description

(1β,4β)-5α,6β-Bis(Diphenylphosphinyl)Bicyclo[2.2.1]Hepta-2-Ene is a sophisticated organophosphorus compound characterized by its unique bicyclic norbornene framework functionalized with two diphenylphosphinyl groups. This structure makes it a valuable chiral ligand and building block in advanced synthetic chemistry, particularly for facilitating asymmetric transformations. It is primarily sought after by research institutions and pharmaceutical development companies engaged in the creation of novel catalysts and complex organic molecules.

Application

• As a chiral ligand in asymmetric metal-catalyzed reactions, including hydrogenation, hydroformylation, and cross-coupling.
• A key intermediate in the synthesis of specialized phosphine ligands for homogeneous catalysis.
• Utilized in academic and industrial research for developing new methodologies in stereoselective synthesis.
• Potential application in the pharmaceutical industry for the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs).
• As a precursor for modified ligands used in material science and polymer chemistry.

Quality Control

Our production of (1β,4β)-5α,6β-Bis(Diphenylphosphinyl)Bicyclo[2.2.1]Hepta-2-Ene adheres to stringent internal quality protocols to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, chiral purity, and impurity profile. We support custom synthesis and can tailor specifications to meet specific research or development project requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container should be stored in a cool, dry place, ideally under an inert atmosphere such as argon or nitrogen to maintain stability. Recommended long-term storage temperature is 2-8°C.
