应用
m-Cresol Purple acts as a pH indicator dye. It plays an important role in spectrophotometric pH measurements. It operates in the pH ranges 1.2 - 2.8 (red to yellow) and 7.4 - 9.0 (yellow to violet). Further, it is employed to stain epithelial cells and proteins. 备注
Transition interval (acid): pH 1.2 (red) to pH 2.8 (yellow); (alkaline) pH 7.4 (yellow) to pH 9.0 (purple)Incompatible with strong oxidizing agents. 基本信息 MDL
