Description
(S)-BINAP is a chiral diphosphine ligand offered at a minimum assay of 98 % for asymmetric catalysis and enantioselective synthesis. The compound carries CAS number 76189-56-5, the empirical formula C₄₄H₃₂P₂ and a molar mass of 622,69 g/mol, providing a well-defined stereochemical scaffold for transition-metal complexes. It is widely applied in rhodium-, ruthenium- and palladium-catalysed hydrogenations as well as carbon–carbon bond-forming reactions where high enantiomeric excess is required. Laboratories value the (S) configuration for reproducible stereocontrol in fine-chemical and medicinal chemistry programmes. Material from manufacturer Carl ROTH integrates readily into glovebox or Schlenk-line workflows and supports the assembly of chiral catalyst libraries. Its dual phosphorus donor sites and rigid biaryl backbone make this BINAP isomer a standard building block for modern organic synthesis and process research.

Questions about (S)-BINAP, min. 98 %, 250 mg, glass
What is this article?
(S)-BINAP, min. 98 %, 250 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
