Description

1,2-Bis((2S,5S)-2,5-Di-I-Propylphospholano)Ethane, Min. 97% is a high-purity, chiral bisphosphine ligand of significant importance in asymmetric catalysis. Its value lies in its ability to induce high enantioselectivity in transition metal-catalyzed reactions, which is critical for the efficient synthesis of single-enantiomer compounds. This product is essential for researchers and process chemists in the pharmaceutical, agrochemical, and fine chemical industries who require reliable and effective ligands for hydrogenation, hydroformylation, and other key synthetic transformations.

Application

• As a chiral ligand for asymmetric hydrogenation reactions in pharmaceutical intermediate synthesis.
• Catalyst component for the enantioselective synthesis of fine chemicals and natural products.
• Use in asymmetric hydroformylation processes to produce chiral aldehydes.
• Key reagent in academic and industrial R&D for developing new catalytic methodologies.
• Potential application in the synthesis of chiral agrochemicals and flavors/fragrances.
