| Hazard Information | Back Directory | [Uses]
1,4,5,8-Tetrachloroanthraquinone is an intermediate used to prepare trianthrimides as potential high-performance pigments. It can also be used to synthesize γ-aminobutyric acid analogs as novel potent GABA-AT (γ-aminobutyrate aminotransferase) inhibitors. | [Synthesis]
Method 1: Put 3000kg of 20% fuming sulfuric acid in chlorination pot, start stirring, then add 250kg anthraquinone, warm up to 90-100℃, continue stirring to dissolve for 1 hour and then add 1kg of iodine of locator agent, after that, pass into chlorine, t |
