Butylated hydroxytoluene (BHT), also known as dibutylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, which is useful for its antioxidant properties. European and U.S. regulations allow small amounts to be used as a food additive. In addition to this use, BHT is widely used to prevent oxidation in fluids (e.g. fuel, oil) and other materials where free radicals must be controlled. Butylated hydroxytoluene has wide application, such as flavors, fragrances, biochemical reagents-other chemical reagents, chemical raw materials, organic chemical raw materials, biochemical, inorganic salts, antioxidants, food additives, feed additives, feed storage additives, aromatic hydrocarbons, bulk drugs and so on. As a phenolic antioxidant, butylated hydroxytoluene can inhibit lipid peroxidation and exhibit electrophilic quinone methyl eth-er toxicity mediated by oxidative metabolism. The BHT metabolites, 6-tert-butyl-2- [2 ′-(2′-hydroxymethyl) -propyl] -4-methylphenol, may cause lung damage in mice and promote tumor growth.
