2-Naphthol
2-Naphthol, or β-naphthol, is a fluorescent colorless crystalline solid with the formula C10H7OH. It is an isomer of 1-naphthol, differing by the location of the hydroxyl group on the naphthalene ring. The naphthols are naphthalene homologues of phenol, but more reactive. Both isomers are soluble in simple alcohols, ethers, and chloroform. 2-Naphthol is a widely used intermediate for the production of dyes and other compounds.
Applications
Dyes
The Sudan dyes are popular dyes noted for being soluble in organic solvents. Several of the Sudan dyes are derived from 2-naphthol by coupling with diazonium salts.Sudan dyes I -IV and Sudan Red G consist of arylazo-substituted naphthols.
Selected 2-Naphthol-derived dyes

Precursor to BINOL
They can be also used in the production of dyes and in organic synthesis.
For example, 2-naphthol reacts to form BINOL.
