(S)-1,1'-Bi-2,2'-naphthol is the optically active S-enantiomer of BINOL, a chiral diol widely used as a ligand, catalyst precursor, and building block in asymmetric synthesis. It is a crystalline solid (C20H14O2, MW 286.32 g·mol⁻¹) typically supplied at high purity for research in organic chemistry and catalysis.
- Chiral diol scaffold for asymmetric catalysis and ligand design.
- High enantiomeric purity suitable for stereoselective reactions.
- Solid crystalline form with defined handling and storage properties.
- Readily derivatized to phosphoramidite and other chiral ligands.
- Applicable to synthesis of natural products and pharmaceutical intermediates.
