Used as a sterically hindered aromatic compound in organic synthesis, particularly in the development of catalysts and ligands for transition metal complexes. Its bulky tert-butyl groups provide strong electron-donating effects and prevent unwanted side reactions by shielding the aromatic ring, making it valuable in stabilizing reactive intermediates. Commonly employed in the study of reaction mechanisms and in the design of advanced materials where controlled molecular geometry is essential. Also finds use in the synthesis of dendrimers and other highly branched macromolecules due to its rigid, symmetrical structure.
