Used primarily as an antioxidant in organic materials, especially in lubricants and fuels, to prevent oxidative degradation. It helps extend the shelf life and stability of products by inhibiting the formation of peroxides and other oxidation byproducts. Commonly found in industrial oils, hydraulic fluids, and gasoline formulations where thermal and oxidative stress are concerns. Also applied in polymers and plastics to maintain physical properties during processing and long-term use. Its branched alkyl chain enhances solubility in nonpolar matrices, making it effective in hydrocarbon-based systems.
