The species behaves as a synthetic analog of vitamin E, primarily acting as a terminating agent that suppresses autoxidation, a process whereby unsaturated (usually) organic compounds are attacked by atmospheric oxygen.<unk>  stops this autocatalytic reaction by converting peroxy radicals to hydroperoxides. It effects this function by donating a hydrogen atom: :RO2• + ArOH → ROOH + ArO• :RO2• + ArO• → nonradical products where R is alkyl or aryl, and where ArOH is<unk>  or related phenolic antioxidants. Each<unk>  consumes two peroxy radicals.
