Description

(2S,3S)-(-)-Bis[(Diphenylphosphino)Amino]Butane CAS NO 72090-84-7 is a chiral, bidentate phosphine ligand with a diamine backbone, prized for its ability to induce high enantioselectivity in transition metal-catalyzed reactions. Its core value lies in enabling the synthesis of optically pure compounds, which is critical for developing pharmaceuticals and advanced materials. This product is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries who require precise stereochemical control.

Application

• As a chiral ligand in asymmetric hydrogenation reactions for the production of enantiomerically pure pharmaceutical intermediates.
• Catalyst component for asymmetric C-C bond-forming reactions, such as cross-coupling and hydroformylation.
• Key reagent in the synthesis of chiral catalysts and auxiliaries for academic and industrial research.
• Use in the development of stereoselective processes for agrochemicals and specialty chemicals.
• Employed in mechanistic studies to understand and optimize enantioselective catalytic cycles.
