2,6-Di-tert-butyl-4-methylcyclohexanol is primarily used as an intermediate in the synthesis of antioxidants, particularly in the production of hindered phenol antioxidants. These antioxidants are widely applied in the stabilization of polymers, such as plastics and rubber, to prevent degradation caused by oxidation. Additionally, it finds use in the formulation of lubricants and fuels, where it helps to enhance the oxidative stability and extend the lifespan of the products. Its role in protecting materials from oxidative damage makes it valuable in industries requiring durable and long-lasting materials.
