anthrone

Anthrone is a tricyclic aromatic ketone, the oxygen-containing derivative of the hydrocarbon anthracene. In its structure, a carbonyl group is embedded in the central ring of the three fused rings, giving the common name 9,10-anthrone. The molecular formula is C14H8O and it appears as yellow to pale orange crystals. It is relatively nonpolar and poorly soluble in water, but dissolves in a range of organic solvents such as benzene and dichloromethane.

Anthrone is an important intermediate in the production of anthraquinone dyes and related polycyclic aromatic pigments. It is also used as a building block in organic synthesis to prepare various derivatives and is sometimes encountered as a byproduct or precursor in dye manufacture.

In analytical chemistry, anthrone dissolved in concentrated sulfuric acid is used in carbohydrate assays (the anthrone reagent). When reacted with hexoses, it yields a blue-green color whose intensity is proportional to carbohydrate concentration.

Safety and handling: Anthrone is an irritant; handle with gloves and goggles in a well-ventilated area; avoid ingestion or inhalation; keep away from strong oxidizers; dispose of according to local regulations.
