Description

(2S,3S)-(-)-Bis(Diphenylphosphino)Butane CAS NO 64896-28-2 is a high-value chiral bidentate phosphine ligand essential for asymmetric catalysis. Its precise stereochemistry enables the production of enantiomerically pure compounds, which is critical for achieving high selectivity and yield in complex synthetic routes. This ligand is indispensable for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries who require advanced chiral intermediates.

Application

• As a chiral ligand in asymmetric hydrogenation reactions for pharmaceutical intermediates.
• Catalyst component in the synthesis of enantiomerically pure agrochemicals and flavors/fragrances.
• Key reagent for cross-coupling reactions (e.g., Suzuki, Heck) requiring stereochemical control.
• Use in academic and industrial R&D for developing novel catalytic asymmetric processes.
• Production of specialty polymers and advanced materials with specific chiral properties.
