Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block for creating more complex aromatic compounds due to the reactivity of the bromine atom, which allows for cross-coupling reactions such as Suzuki or Heck reactions. Also employed in the development of specialty polymers and additives where steric hindrance from the tert-butyl group enhances stability. Its phenolic structure makes it useful in the synthesis of antioxidants and UV stabilizers for industrial materials.
