Widely used in chemical experiments, water quality testing, and industrial titration analysis.
Color Change: Colorless in acidic → Colorless in neutral → Pink/Purple-red in alkaline solutions.
Historically used as a stimulant laxative to stimulate colonic mucosa and promote peristalsis. Currently, it is primarily used as a pharmaceutical raw material and research reagent, with clinical usage significantly reduced.
Serves as an analytical reagent and titration indicator. It is also used for pH indication in the electroplating industry, as well as in teaching experiments and chemical detection kits.
