Product Application of Carboxymethyl Cellulose CAS#128-37-0
Butylated hydroxytoluene (BHT) has a wide range of applications, including use in flavors and fragrances, biochemical reagents, chemical and organic raw materials, antioxidants, food additives, feed additives, and feed preservation, as well as in aromatic hydrocarbons and bulk pharmaceuticals. As a phenolic antioxidant, BHT effectively inhibits lipid peroxidation and exhibits electrophilic quinone methide toxicity through oxidative metabolism. Its metabolite, 6-tert-butyl-2-[2′-(2′-hydroxymethyl)-propyl]-4-methylphenol, has been reported to cause lung damage in mice and may promote tumor development.
