naphthol

 [naf´thol]

naph·thol

(naf'thol),
A hydroxynaphthalene, occurring in two forms: α-naphthol, a dye intermediate used in cytochemistry for l-arginine localization; and β-naphthol, also known as isonaphthol, used as an anthelmintic and antiseptic. Both forms are also used in the manufacture of dyes, organic chemicals, and rubber products.
