Binol is a racemate of two enantiomers, d-Binol and l-Binol. Binol exhibits high selectivity for β1-adrenergic receptors and has vasodilating activity due to a direct action on the endothelium, involving nitric oxide release. It lacks intrinsic sympathomimetic and membrane-stabilising activity.

1,1′-Bi-2-naphthol (BINOL) is an organic compound that is often used as a ligand for transition-metal catalysed asymmetric synthesis. BINOL has axial chirality and the two enantiomers can be readily separated and are stable toward racemisation. The specific rotation of the two enantiomers is 35.5° (c = 1 in THF), with the R enantiomer being the dextrorotary one. BINOL is a precursor for another chiral ligand called BINAP. The volumetric mass density of the two enantiomers is 0.62 g cm .
