1,3-DIHYDROXYNAPHTHALENE Chemical Properties,Uses,Production

Chemical Properties

orange-pink to brown crystalline powder. 1,3-Naphthalenediol [132-86-5], naphthoresorcinol, mp 124℃, is synthesized by hydrolysis of 1,3-naphthalenediamine with sulfuric acid; by heating 1-amino-3-hydroxy-naphthalene-4-sulfonic acid with acid; or by cyclization of ethyl phenylacetoacetate. It is used as an analytical reagent for sugars and glucuronic acid in urine. It is oxidized in alkaline solution to 2-hydroxy-1,4-naphthoquinone and reacts with ammonia at 140℃ to give 3-amino-1- naphthol and 1,3-naphthalenediamine.

Uses

Reagent for sugars, oils, and for glucuronic acid in urine: Forsyth, Nature 161, 239 (1948); Heyns, Kelch, Z. Anal. Chem. 139, 339 (1953).

Uses

1,3-Naphthalenediol is a derivative of naphthalene (N345600) and may have antibacterial activity against oral bacteria.Dyes and metabolites.
