Used as a pH indicator in analytical chemistry due to its distinct color change in different pH environments. The compound shows visible shifts in hue between acidic and basic conditions, making it suitable for titration experiments and acid-base detection in laboratory settings. Its azo group contributes to chromogenic properties, allowing for easy visual or spectrophotometric monitoring. Also investigated for potential use in dye-sensitized solar cells and as a precursor in the synthesis of functional organic materials with light-responsive behavior.
