4-tert-Butylcatechol

4-tert-Butylcatechol (TBC) is an organic chemical compound which is a derivative of catechol. TBC is available in the form of a solid crystal flake and 85% solution in methanol or water.

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

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

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