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.
(S)-(-)-BINOL CAS: 18531-99-2 is a chiral BINOL widely used as ligand for asymmetric reaction, or organic catalyst, to induce new chiral center formation during the organic reaction. And also it is raw material for chiral BINAP, which is very famous organic phosphino ligand.
The supplying capacity is around 1000Kgs per month and its chemical purity is reached over 99%, and optical purity over 99.5%ee, which could be delivered by air or by sea upon the ordered quantity and your requirement.
UCHEM could supply both enanthiomers of BINOL regularly, and also other BINOL derivatives.
