Used primarily as an antioxidant and stabilizer in polymers and plastics, it helps prevent degradation caused by heat, light, and oxidation. It is commonly applied in the production of rubber, adhesives, and coatings to extend their lifespan and maintain performance under harsh conditions. Additionally, it finds use in the synthesis of specialty chemicals and as an intermediate in organic reactions. Its ability to inhibit oxidative processes makes it valuable in industrial applications where material durability is critical.
