Used as a key reagent in organic synthesis, particularly in the preparation of functionalized imidazoles and N-heterocyclic carbene precursors. It serves as a protecting group carrier in nucleotide and peptide chemistry due to the stability of the trityl group under various reaction conditions. The bromine atoms allow further functionalization via cross-coupling reactions such as Suzuki or Heck reactions, making it valuable in medicinal chemistry for building complex molecules. Also employed in the synthesis of ligands for catalysis and in materials science for constructing tailored organic frameworks.
