What is the tert-Butylhydroquinone?

tert-Butylhydroquinone is tan powder, while it's Molecular Formula is C10H14O2. tan powder TBHQ was used to study the inactivation of barotolerant strains of Listeria monocytogenes and Escherichia coli. Environment friendly electrode materials for supercapacitors were attained by decorating the surface of graphene nanosheets with TBHQ. TBHQ is frequently used as a food preservative. Inhibition of oxidative rancidity in frozen cooked fish flakes by tert-butylhydroquinone. Nuclear factor E2-related factor 2-dependent antioxidant response element activation is by tert-butylhydroquinoneoccurring preferentially in Astrocytes conditions.

What is the CAS number for tert-Butylhydroquinone?

The CAS number of tert-Butylhydroquinone is 1948-33-0.

What is tert-Butylhydroquinone (1948-33-0) used for?

tert-Butylhydroquinone (TBHQ) is a white to light tan crystalline powder or a fine beige powder with a very slight aromatic odor. It is a member of the class of hydroquinones in which one of the ring hydrogens of hydroquinone is replaced by a tert-butyl group. TBHQ is an antioxidant used to preserve oils, fats, and food items, and is found in various applications such as vegetable oils, animal fats, varnishes, lacquers, resins, oil field additives, and perfumes. In low concentrations, it shows cytoprotective qualities, while at higher concentrations, it exhibits cytotoxic behavior.InChI:InChI=1/C10H12O3/c1-10(2,3)8-6(11)4-5-7(12)9(8)13/h4-5,13H,1-3H3

tert-Butylhydroquinone(Cas 1948-33-0) Usage

Air & Water Reactions	Insoluble in water.
Reactivity Profile	Phenols, such as tert-Butylhydroquinone, do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has Ka = 1.3 x 10^[-10]). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases. Such heating may initiate polymerization of the organic compound. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). The reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid. Nitrated phenols often explode when heated. Many of them form metal salts that tend toward detonation by rather mild shock. tert-Butylhydroquinone is incompatible with oxidizers.
Fire Hazard	tert-Butylhydroquinone is combustible.
Flammability and Explosibility	Nonflammable
Contact allergens	This antioxidant has seldom been reported as a sensitizer, mainly in cosmetics (lipsticks, lip-gloss, hair dyes) or in cutting oils. Simultaneous/cross-reactions have been described to butylhydroxyanisole (BHA) and less frequently to butylhydroxytoluene (BHT), but not to hydroquinone
Purification Methods	Recrystallise the hydroquinone from H2O or MeOH and dry it in a vacuum at 70o. Store it in a dark container. [Stroh et al. Angew Chem 69 699 1957, Beilstein 6 IV 6013.]
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.
General Description	White to light tan crystalline powder or a fine beige powder. Very slight aromatic odor.
