Description

(R)-Cyclohexyl Soniphos is a chiral phosphine ligand, a key component in asymmetric catalysis for the synthesis of enantiomerically pure compounds. Its value lies in enabling highly selective chemical transformations, which are critical for producing active pharmaceutical ingredients (APIs) and advanced fine chemicals with the desired stereochemistry. This product is essential for research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors who require high-performance catalysts for complex synthetic routes.

Application

• As a chiral ligand in asymmetric hydrogenation reactions for pharmaceutical intermediates.
• Catalyst component in enantioselective C-C and C-X bond-forming reactions.
• Use in the synthesis of chiral active pharmaceutical ingredients (APIs).
• Research and development of novel catalytic processes in academic and industrial labs.
• Production of enantiomerically pure agrochemicals and flavors/fragrances.
• As a specialty additive in advanced material synthesis requiring chiral control.
