2,6-Di-tert-butyl-4-methylphenol, commonly known as BHT (Butylated Hydroxytoluene), is a lipophilic antioxidant used to prevent oxidation in fats, oils, and other organic compounds. It protects products from rancidity and extends shelf life in foods, cosmetics, and pharmaceuticals. BHT is highly effective in stabilizing materials against oxidative degradation. Its high-purity grade ensures safety and efficacy in industrial and consumer applications.
