Widely used as a pH indicator in analytical chemistry, this compound exhibits a distinct color change in response to acidity or alkalinity, making it valuable in titration experiments and pH measurement in laboratory settings. It is particularly effective in detecting shifts in mildly acidic to neutral ranges. Due to its azo group and imidazolium structure, it also finds use in research involving ionic liquids and as a dye in specialized staining techniques. Its strong chromophoric properties allow for sensitive detection in spectrophotometric analyses. Additionally, it serves as a model compound in studies of azo dye degradation and environmental impact of synthetic dyes.
