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.
