CAS 128-38-1: 4,4′-Bis(2,6-di-tert-butylphenol)

Description: 4,4′-Bis(2,6-di-tert-butylphenol), commonly referred to as BHT (butylated hydroxytoluene), is an organic compound characterized by its antioxidant properties. It features two bulky tert-butyl groups attached to a phenolic structure, which enhances its stability and effectiveness in preventing oxidative degradation of various materials. This compound is typically a white to pale yellow crystalline solid at room temperature and is soluble in organic solvents but has limited solubility in water. BHT is widely used in the food industry as a preservative to extend the shelf life of fats and oils by inhibiting rancidity. Additionally, it finds applications in cosmetics, pharmaceuticals, and rubber manufacturing due to its ability to protect against oxidative damage. While generally recognized as safe in regulated amounts, BHT has been the subject of some controversy regarding its potential health effects, leading to ongoing research into its safety profile. Overall, its unique structure and properties make it a valuable compound in various industrial applications.
