Chloranilic acid: Does not have an individual approval but may be used under an appropriate group standard
解説2,5-dichloro-3,6-dihydroxy-p-benzoquinone.C6H2Cl2O4(208.98).クロラニル酸,クロラニルをアルカリ水溶液で加水分解すると得られる.水から再結晶すると2分子の水和水をもつ赤色の葉状晶が得られる.分解点283~284 ℃.熱水に溶けて紫色を呈する.比較的強い二塩基酸であり,金属イオンと安定な塩をつくるため,金属の分析用試薬として用いられる.金属塩はSO42-,PO43-などの陰イオンの比色定量に用いられる.肝機能検査用試薬としても用いられる.森北出版「化学辞典(第2版)
使用Chloranilic acid is the reactant involved in:Acting as a proton donor in reactions studying dimensionality controlSynthesis of dimethylbipyridyl complexesSynthesis of (nonylbenzimidazolylmethyl)benzene for preparation of neutral altitudinal rotor-shaped dirhenium metallacyclesCharge-transfer reactions with metoprolol tartrateSalt formation with organic basesSynthesis of osmium metalla-rectangles with anticancer activity
純化方法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. [Weissbart & Rysselberghe J Phys Chem 61 765 1957.] The diacetate has m 182-185o [Conant & Fieser J Am Chem Soc 46 1866 1924, Thamer & Voight J Phys Chem 56 225 1952]. [Beilstein 8 IV 2707.]
