Used primarily as an antioxidant in organic materials, especially in polymers, fuels, and oils to prevent degradation caused by oxidation. It effectively stabilizes products against thermal and oxidative stress during processing and long-term storage. Commonly found in lubricants, rubber, and plastic systems where it helps extend service life by inhibiting discoloration, embrittlement, and viscosity changes. Also employed in some formulations of cosmetics and pharmaceuticals as a stabilizer to protect active ingredients from oxidation. Its high volatility limits use in high-temperature applications, but it remains effective in low- to medium-temperature environments.
