Used in analytical chemistry as a reagent for the determination of certain pharmaceuticals and biomolecules due to its ability to participate in color-forming reactions. It serves as an intermediate in the synthesis of dyes and other heterocyclic compounds. Also employed in research settings for developing new chemical sensors and assays, particularly for detecting phenolic compounds and peroxidase activity. Its bromine substituent allows for further functionalization through coupling reactions, making it valuable in medicinal chemistry for building more complex molecules.
