Chloranilic acid Chemical Properties,Uses,Production

Chemical Properties

orange or red crystals or powder

Uses

Chloranilic acid is the reactant involved in:
Acting as a proton donor in reactions studying dimensionality control
Synthesis of dimethylbipyridyl complexes
Synthesis of (nonylbenzimidazolylmethyl)benzene for preparation of neutral altitudinal rotor-shaped dirhenium metallacycles
Charge-transfer reactions with metoprolol tartrate
Salt formation with organic bases
Synthesis of osmium metalla-rectangles with anticancer activity

Purification Methods

A solution of 8g of quinone in 1L of boiling water is filtered while hot, then extracted twice at about 50o with 200mL portions of *benzene. The aqueous phase is cooled in ice-water. The crystals are filtered off, washed with three 10mL portions of water, and dried at 115o. It can be sublimed in vacuo.
