甲酚红钠盐

Cresol Red sodium salt acts as a constituent of polymerase chain reaction reagent systems. It is useful as a pH indicator with color changes with pH 0.2 - pH 1.8 and pH 7.1 - 8.8. Further, it plays an important role in molecular biology reactions in place of other loading dyes.

Transition interval (acid): pH 0.2 (red) to pH 1.8 (yellow); (alkaline) pH 7.2 (yellow) to pH 8.8 (red)Incompatible with strong oxidizing agents.
