Used as a stabilizer and antioxidant in polymer systems, particularly in polycarbonates and polyesters. It protects materials against thermal and oxidative degradation during processing and extends product lifespan by preventing discoloration and molecular weight loss. Also employed in electronic materials as a ligand in catalysts for cross-coupling reactions, supporting the synthesis of fine chemicals and pharmaceuticals. Its electron-donating structure enhances performance in optoelectronic applications, including organic light-emitting diodes (OLEDs).
