Used primarily in organic synthesis as a diazonium salt, it serves as a key intermediate for introducing the bromophenyl group into various compounds. It is particularly valuable in Sandmeyer reactions, where it facilitates the substitution of diazonium groups with halides, enabling the synthesis of aryl bromides. This compound is also employed in the preparation of dyes, pharmaceuticals, and agrochemicals, where the bromophenyl moiety is essential for desired properties. Additionally, it is utilized in coupling reactions to create complex organic molecules, including polymers and advanced materials. Its stability and reactivity make it a versatile reagent in research and industrial applications.
