                                                    Dihydroxynaphthalenes 
                        are compounds which two hydroxyl groups are substituted 
                        to naphthalene ring system. There are positional isomers differing by 
the location of the hydroxyl group. The different positions provide various chemical structures which offer 
important roles to each characteristics. They are used directly in making several dyes and are converted into numerous 
corresponding amines, esters, ethers and carboxylic derivatives as well as into 
numerous sulfo- and nitro-group substituted (mono-, di- and tri) compounds. They find extensive applications in making dyes, pigments, 
fluorescent whiteners, tanning agents, antioxidants, and antiseptics. Dihydroxynaphthalene 
                        structure is found as a ligand in transition-metal catalysts 
particularly in the form of binaphthalenediol which is composed of two 
naphthalenediol rings connected at one carbon site on each ring.
