Used primarily as an antioxidant in organic materials, especially in polymers and lubricants, to prevent degradation caused by oxidation. It protects against thermal and oxidative stress during processing and extends the service life of products. Commonly added to plastics, rubber, and industrial oils to maintain stability and performance under high temperatures and prolonged storage. Also employed in some formulations as a stabilizer for hydrocarbons and resins. Its high steric hindrance makes it effective in scavenging free radicals, enhancing the durability of sensitive compounds.
