S-BINAP CAS: 76189-56-5 is white crystal powder with formula (C44H32P2). It could be dissolved into most of organic solvent.
S-BINAP is prepared with same way as R-BINAP. The both enantiomers has been extensively studied in asymmetric synthesis, e.g. asymmetric hydrogenation, protonation silyl enol ethers. Some of catalysts have been applied in industrial process.
S-BINAP has same structure and application area except its optical rotation. Due their widely applications, their synthesis are also extensively studied and robust process cut down its cost accelerating its application area.
UCHEM has been supplying both enantiomers and racemic BINAP.
