tert-Butylhydroquinone(Cas 1948-33-0) Usage
| General Description |
tert-Butylhydroquinone (TBHQ) is a white, crystalline solid with a characteristic odor. It is a versatile antioxidant used in the preservation of fats, oils, and food products, with additional applications in research and materials science. TBHQ can be found naturally in vegetable oils, animal fats, varnishes, lacquers, resins, oil field additives, and perfumes. |
|
Uses |
tert-Butylhydroquinone (TBHQ) exhibits excellent stabilizing effects in unsaturated fats and oils. It serves as an antioxidant and is commonly used to preserve oils, fats, and various food items. TBHQ has also been utilized in the development of environmentally friendly electrode materials for supercapacitors. By decorating the surface of graphene nanosheets with TBHQ, enhanced properties for supercapacitors have been achieved. |
|
Definition |
ChEBI: A member of the class of hydroquinones in which one of the ring hydrogens of hydroquinone is replaced by a tert-butyl group. |

Chemoprotective and Carcinogenic Effects of tert-Butylhydroquinone and Its Metabolites

Tert-butylhydroquinone (tBHQ) has been commonly used as a synthetic food antioxidant to prevent oils and fats from oxidative deterioration and rancidity due to its potent anti-lipid peroxidation activity. In North America, the maximum level of tBHQ allowed in fat products is 0.02% with an acceptable daily intake of 0 - 0.7 mg/kg body weight. Extensive studies have demonstrated that tBHQ exhibit anti-carcinogenic effect.

2-tert-Butylhydroquinone (TBHQ) is a strong antioxidant that is used as a food additive in oils, fat and meat products, primarily to prevent rancidity. Metabolically, TBHQ is formed from 3-tert-butyl-4-hydroxyanisole (BHA), another widely used food additive, by O-demethylation (Armstrong and Wattenberg, 1985), and it is further oxidized to 2-tert-butyl-1,4-benzoquinone (TBQ) (Kahl et al., 1989).
