2,6-Di-tert-butyl-4-methyl-d3-phenol

2,6-Di-tert-butyl-4-methyl-d3-phenol, commonly known as BHT-d3, is an antioxidant and stabilizer used in various industries such as cosmetics, food, and pharmaceuticals. It is a deuterated analog of the popular antioxidant BHT (butylated hydroxytoluene). The deuterium substitution in BHT-d3 makes it useful for quantification purposes in various analytical techniques such as NMR spectroscopy. BHT-d3 works by inhibiting the oxidation of various compounds by free radicals. It does so by scavenging these free radicals, thereby preventing them from reacting with other compounds. As a result, BHT-d3 is widely used in the stabilization of fats, oils, and other lipids in food and cosmetics. It is also used in the production of rubber and plastics to prevent degradation due to exposure to oxygen and heat. From a chemical standpoint, BHT-d3 is a phenolic compound with a molecular weight of 220.4 g/mol. It is soluble in organic solvents such as ethanol and acetone but insoluble in water. BHT-d3 is relatively stable at room temperature and has a melting point of approximately 69°C. In conclusion, BHT-d3 is a versatile and useful antioxidant that finds application in various industries. Its deuterium substitution makes it a valuable tool for analytical purposes. Its chemical properties make it an effective stabilizer for lipids, plastics, and rubber.
