Used as an intermediate in organic synthesis, particularly in the preparation of complex molecules for pharmaceuticals and agrochemicals. It serves as a building block in cross-coupling reactions, such as Suzuki or Heck reactions, to create biaryl compounds. Its halogenated structure makes it valuable for introducing functional groups or modifying aromatic systems in drug discovery and material science. The tert-butyl group provides steric hindrance, influencing the selectivity and reactivity in synthetic pathways.
