Brit.

/ˈanθrənɒl/, U.S.

/ˈænθrəˌnɔl/,

/ˈænθrəˌnɑl/

Origin: A borrowing from German. Etymon: German Anthranol.

Etymology: < German Anthranol (C. T. Liebermann & Topf 1876, in Berichte der Deutsch. Chem. Ges. 9 1202), probably < Anthra- anthra- comb. form + -en -ene comb. form + -ol -ol suffix (compare later enol n.).

Chemistry.

A yellow crystalline compound which is a monohydroxy derivative of anthracene. Cf. anthrol n.Systematic name: 9-hydroxyanthracene; C₁₄H₁₀O. It is the enol counterpart of anthrone, into which it can easily be transformed.

1877 Amer. Chemist Jan. 278/1 A new product, intermediate between anthraquinone and bihydride, was formed..called anthranol.

1922 J. J. Sudborough Bernthsen's Text-bk. Org. Chem. (new ed.) xxxii. 536 γ-Hydroxy-anthracene or anthranol may be obtained by reducing anthraquinone with zinc and acetic acid.

1937 Thorpe's Dict. Appl. Chem. (ed. 4) I. 432/1 The O-ethers of anthranol couple readily with diazonium salts.

2006 Remington: Sci. & Pract. Pharmacy (ed. 21) xxvi. 439/1 Anthranol derivatives are commonly found in aloes.

2006 Inorg. Chem. 45 8317/1 These oxidations probably proceed via anthranol.
