tert-Butylhydroquinone

Description:

Tert-Butylhydroquinone (TBHQ) is an organic compound classified as a phenolic antioxidant, commonly used in food preservation and industrial applications. It is characterized by its chemical formula C10H14O2 and a molecular weight of approximately 166.22 g/mol. TBHQ appears as a white to pale yellow crystalline solid and is soluble in organic solvents such as ethanol and ether, but has limited solubility in water. Its structure features a tert-butyl group attached to a hydroquinone moiety, which contributes to its antioxidant properties by preventing oxidative degradation of fats and oils. TBHQ is known for its stability and effectiveness in extending the shelf life of various products, including edible oils, snacks, and cosmetics. However, its use is regulated in many countries due to potential health concerns associated with high consumption levels. Safety assessments indicate that TBHQ is generally recognized as safe (GRAS) when used within established limits, but excessive intake may lead to adverse effects. Overall, TBHQ serves as a valuable additive in various industries, balancing efficacy with safety considerations.

Applications tBHQ is an antioxidant in induction of AP-1, NF-κB, and glutathione S-transferase gene expression. It also disrupts ability of Kelch-like ECH-associated protein 1(Keap1) to target Nrf2, a bZIP transcription factor, for proteasome-mediated degradation and promote nuclear accumulation of Nrf2.

tert-Butylhydroquinone

CAS: 1948-33-0

tert-ButylhydroQuinone (TBHQ) is an antioxidant that has been shown to have synergistic effects with other antioxidants such as vitamin E and vitamin C. TBHQ is a quinone that can be found in foods, especially those rich in oils or fats, such as vegetable oils, soybean oil, and sunflower oil. TBHQ acts as an antioxidant by donating hydrogen atoms to free radicals. It has been shown to protect the liver from oxidative stress caused by the toxic metabolite of acetaminophen (paracetamol). TBHQ also protects against myocardial infarcts, which are caused by decreased blood flow to the heart muscle due to plaque buildup.
