2-Naphthol (2OH) is a hydroxyarene molecule, which when electronically excited forms strong acid. Excited 2OH dissociates only in water.It has a slight phenolic odor. It is incompatible with strong oxidizing agents, strong bases, acid chlorides and acid anhydrides
2-Naphthol, or β-naphthol, is a fluorescent colorless (or occasionally yellow) 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.2-naphthol is a naphthol carrying a hydroxy group at position 2.
