off-white to light yellow crystals

Uses

Anthrone is a tricyclic aromatic ketone and related compound of anthracene. Anthrone is used as a reagent in the colorometric determination of carbohydrates.

Definition

ChEBI: A member of the class of anthracenes that is 9,10-dihydroanthracene carrying an oxo group at C-9.

General Description

Anthrone has the ability to reduce aldehyde containing reducing sugars such as streptose and N-acetyl glucosamine present in streptomycin, into acids. It develops a red- violet color. Therefore, it is used to determine streptomycin quantitatively. Anthrone has been used to detect carbohydrate containing lipids and to measure sugar content such as sucrose and trehalose in the liquid medium.

Safety Profile

Mutation data reported. Whenheated to decomposition it emits acrid smoke andirritating vapors.

Synthesis

104g anthraquinone, 100g tin particles, 750ml glacial acetic acid mixed heated to boiling, and then add concentrated hydrochloric acid 250ml (relative density of 1.19) one by one, about 2h to add, at this time, the anthraquinone should be all dissolv

Purification Methods

This stable keto tautomer of 9-anthranol (above) provides yellow crystals from a 3:1 mixture of *C6H6/pet ether (b 60-80o) (10-12mL/g), or successively from *C6H6 then EtOH. Dry it in vacuo. [Meyer Org Synth Coll Vol I 60 1941, Beilstein 6 IV 4930.]
