Description

(R)-C3-Tunephos CAS NO 486429-99-6 is a high-value, chiral phosphine ligand used in asymmetric catalysis. Its primary value lies in enabling highly enantioselective transformations, which are critical for the efficient synthesis of single-enantiomer pharmaceutical intermediates and fine chemicals. This product is essential for R&D and production chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require precise stereochemical control.

Application

• As a chiral ligand in asymmetric hydrogenation reactions for pharmaceutical API synthesis.
• Catalyst component in enantioselective cross-coupling reactions (e.g., Suzuki-Miyaura, Heck).
• Key reagent for the preparation of chiral organometallic complexes.
• Use in asymmetric allylic substitution reactions to construct chiral carbon centers.
• Research and development of novel catalytic systems in academic and industrial laboratories.
• Production of enantiomerically pure agrochemical intermediates.
• Development of specialty polymers and materials with controlled chirality.
