tan to yellow crystals | [Uses]
As indicator, pH 3.8 yellow; pH 5.4 blue-green. | [Definition]
ChEBI: Bromocresolgreen is a member of benzofurans. | [Hazard]
Moderately toxic. | [Synthesis]
A method of preparing bromocresol green in the following steps:
(1) 1.5 kg of bromine is dissolved in 1.25 liters of glacial acetic acid solution to obtain a bromine-glacial acetic acid mixture;
(2) 2 kg of pure m-cresol violet is disso | [Purification Methods]
Crystallise the dye from glacial acetic acid or dissolve it in aqueous 5% NaHCO3 solution and precipitate it from the hot solution by dropwise addition of aqueous HCl. Repeat this until the UV/VIS-extinction did not increase 423nm. It is an indicator: at pH 3.81 at max (yellow) and pH 5.4 (blue-green). [Beilstein 19/3 V 460.] |
