Product Description:
This chemical is primarily used as a chiral ligand in asymmetric synthesis, particularly in catalytic reactions such as hydrogenation, hydroformylation, and cross-coupling reactions. Its structure, featuring diphenylphosphino groups, makes it effective in coordinating with transition metals like rhodium, palladium, and ruthenium, enhancing the enantioselectivity of the catalytic process. It is often employed in the production of pharmaceuticals and fine chemicals, where achieving high enantiomeric purity is critical. Additionally, its isopropylidene-protected diol moiety provides stability and controlled reactivity in complex synthetic pathways.
