Safety Information
Acid chrome blue K Usage And Synthesis
| Uses | Acid chrome blue K is a metal indicator. The solution color of the LAMP (Loop-mediated isothermal amplification) reaction with ACBK (Acid chrome blue K) changes from red to blue based on a decrease in the Mg2+ concentration in the reaction solution[1]. |
| Preparation | 3-Amino-4-hydroxybenzenesulfonic acid diazotization, and 4,5-Dihydroxynaphthalene-2,7-disulfonic acid coupling. |
| Properties and Applications | red light navy blue. Soluble in water and ethanol. In concentrated sulfuric acid to purple, dilution after blue light pink; In concentrated nitric acid for dark orange to yellow brown. Dye aqueous solution and sodium hydroxide as yellow solution.
