Used primarily as an antioxidant in polymers and organic materials, this compound helps prevent degradation caused by oxidation, extending the lifespan of plastics, rubber, and adhesives. It is especially effective in high-temperature processing and long-term thermal aging applications. Commonly found in polyolefins such as polyethylene and polypropylene, it maintains material integrity by inhibiting discoloration, embrittlement, and loss of mechanical strength. Also employed in coatings and elastomers where oxidative stability is critical. Its sterically hindered phenolic structure provides efficient radical scavenging, making it suitable for demanding industrial and automotive applications.
