R-(+)-1,1’-Bi-2-naphthol（Cat No.:R061903）, commonly known as (R)-BINOL, is a chiral, axially symmetric biaryl compound with the molecular formula C20H14O2. It consists of two naphthol units connected at the 1-position, with hydroxyl groups at the 2-positions, creating a rigid, non-planar structure. This enantiomerically pure compound is widely used as a chiral ligand or catalyst in asymmetric synthesis, particularly in reactions such as enantioselective hydrogenation, allylation, and cycloadditions. Its optical activity and ability to coordinate with metals make it essential in preparing stereochemically defined pharmaceuticals and fine chemicals. It appears as a white to off-white crystalline solid.
