Used as a stabilizer in polymers and organic materials due to its antioxidant properties. The phenolic structure with tert-butyl groups enables the formation of stable phenoxy radicals after hydrogen abstraction, enhancing its efficiency in scavenging free radicals. It helps prevent degradation caused by oxidation, extending the lifespan of plastics, rubbers, and lubricants exposed to heat and UV light. Also employed in specialty chemical synthesis where sterically hindered phenols are required, such as in the development of pharmaceuticals or agrochemicals. Its bulky structure enhances radical scavenging efficiency, making it effective in low concentrations.
