Uses

It is added as a stabilizer and polymerisation inhibitor to butadiene, styrene,[5] vinyl acetate, divinylbenzene[6] and other reactive monomer streams.[7]

TBC is also used as a stabilizer in the manufacture of polyurethane foam.[8] It also can be used as an antioxidant for synthetic rubber, polymers and oil derivatives.[7] It can be used as purification agent for aminoformate catalysts.

It is 25 times better than hydroquinone at 60 °C for polymerization inhibitory effect.
