Binaphthol, 2,2'-dihydroxy-1,l'-dinaphthalene as its scientific name, 

has a melting point of 2l7.5 to 2l9 degrees. Its molecular formula is 

C20H14O2.



Binaphthol is a typical chiral compound with strong dissymmetry and can 

be resolved easily into antipodes in high purity.  Binaphthol also has 

important applications in many businesses such as organic syntheses, dyes, 

agriculture chemicals, etc., especially in special medicines.  As a 

resolving reagent, the two hydroxyls of binaphthol can combine with some 

compounds by means of hydrogen bonds to form molecular complexes. As an 

unsymmetrical inducing reagent, binaphthol takes part in unsymmetrical 

synthetics of some compounds such as biaromatics, unsaturated aldehydes etc., 

which provides a new valuable route for researches of unsymmetrical

synthetic chemistry and natural substances synthetics.
