4-tert-Butylcatechol (TBC) is an organic chemical compound which is a derivative of catechol. It is added as a stabilizer and an inhibitor of polymerization to butadiene, styrene, vinyl acetate and other reactive monomer streams. It is 25 times better than hydroquinone at 60°C for polymerization inhibitory effect. 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. TBC is available in a form of a solid crystal and 85% solution in methanol or water.
