| | METHYLTHYMOL BLUE Usage And Synthesis |
| Chemical Properties | green-brown crystalline powder | | Uses | Methylthymol Blue sodium salt is used as thymol-containing organic dye. It is used as an indicator for complexometry. It is used in determination of sulfate in rainwater. It combines with silica gel and aids in the separation and preconcentration of trace amounts of heavy metals from some salts. | | Purification Methods | Methyl Thymol Blue, sodium salt [1945-77-3] M 844.8, 1.89 x 104 at 435nm, pH 5.5, 252525 25 25 25 25pK 1 3.0, pK 2 3.3, pK 3 3.8, pK 4 7.4 (pK 4 7.2) , pK 5 11.5 pK 6 13.4.
