CAS 1948-33-0: terc-butilhidroquinona
Descripción:
terc-butilhidroquinona (TBHQ) es un compuesto orgánico clasificado como un antioxidante fenólico, comúnmente utilizado en la conservación de alimentos y aplicaciones industriales. Se caracteriza por su fórmula química C10H14O2 y un peso molecular de aproximadamente 166.22 g/mol. El TBHQ aparece como un sólido cristalino blanco a amarillo pálido y es soluble en disolventes orgánicos como el etanol y el éter, pero tiene una solubilidad limitada en agua. Su estructura presenta un grupo tert-butilo unido a una parte de hidroquinona, lo que contribuye a sus propiedades antioxidantes al prevenir la degradación oxidativa de grasas y aceites. El TBHQ es conocido por su estabilidad y efectividad en la prolongación de la vida útil de varios productos, incluidos aceites comestibles, bocadillos y cosméticos. Sin embargo, su uso está regulado en muchos países debido a posibles preocupaciones de salud asociadas con niveles altos de consumo. Las evaluaciones de seguridad indican que el TBHQ es generalmente reconocido como seguro (GRAS) cuando se utiliza dentro de los límites establecidos, pero una ingesta excesiva puede llevar a efectos adversos. En general, el TBHQ sirve como un aditivo valioso en diversas industrias, equilibrando la eficacia con consideraciones de seguridad.

CAS: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.Fórmula:C10H14O2Pureza:Min. 95%Forma y color:PowderPeso molecular:166.22 g/mol
