Used as a pH indicator in various analytical chemistry applications, particularly in titrations to detect the endpoint of acid-base reactions. Its color change from colorless to pink or purple in alkaline conditions makes it valuable for determining pH shifts in laboratory experiments. Additionally, it serves as a dye intermediate in the synthesis of other compounds, contributing to the production of specialized pigments or materials. Its brominated structure also lends itself to flame retardant applications, where it can be incorporated into polymers or coatings to enhance fire resistance.
