Used as an antioxidant in polymers and plastics to prevent degradation from heat and UV exposure. Commonly found in stabilizer formulations for polyolefins such as polyethylene and polypropylene. Also serves as an intermediate in the synthesis of more complex antioxidants and UV absorbers. Its phenolic structure contributes to radical scavenging properties, enhancing material longevity in outdoor applications. Employed in coatings, adhesives, and rubber products to maintain mechanical strength and color stability over time.
