The field of organic synthesis is constantly pushing boundaries, demanding increasingly sophisticated tools for achieving precise molecular construction. Chiral phosphine ligands are at the forefront of this evolution, enabling chemists to control the stereochemical outcome of reactions. (S)-(-)-2,2'-Bis[di(3,5-xylyl)phosphino]-1,1'-binaphthyl, known by its CAS number 135139-00-3 and often referred to as (S)-Xylyl-BINAP, is a standout ligand in this category. Its molecular formula is C52H48P2, with a molecular weight of 734.89, and it typically appears as a white to pale yellow crystalline powder.

The utility of (S)-Xylyl-BINAP extends across various critical applications. It serves as a highly effective chiral auxiliary in asymmetric catalysis, facilitating reactions such as the enantioselective synthesis of chiral amines, alcohols, and carboxylic acids. These are vital building blocks for the pharmaceutical industry, where enantiomeric purity is paramount for drug efficacy and safety. Furthermore, this ligand finds application in the development of materials for optoelectronic devices, including OLEDs, where precise molecular architecture dictates performance. Researchers and chemical engineers seeking to buy (S)-Xylyl-BINAP will find its consistent high purity (often exceeding 97%) and defined stereochemistry invaluable for reproducible results.
