Used primarily as an antioxidant in industrial applications, this compound prevents degradation of organic materials by inhibiting oxidation processes. It is commonly added to lubricants, fuels, and polymers to extend shelf life and maintain performance under high-temperature or oxidative conditions. Its sterically hindered structure enhances stability and effectiveness, making it suitable for use in engine oils and transmission fluids where long-term protection is required. It also finds application in the stabilization of dyes, resins, and rubber products against discoloration and aging.
