Used primarily as a secondary antioxidant in plastics and rubber, this compound helps prevent degradation caused by heat and oxidation during processing and service life. It is especially effective in polyolefins, such as polyethylene and polypropylene, where it stabilizes the material against discoloration and molecular breakdown. It also finds use in synthetic lubricants and adhesives to extend product lifespan by inhibiting oxidative deterioration. Its compatibility with other stabilizers allows synergistic effects when combined with primary antioxidants like hindered phenols.
