2,5-di-t-butyl-4-hydroxyphenyl acetate, also known as BHT or butylated hydroxytoluene, is a widely used synthetic antioxidant and preservative. It is an organic compound with the chemical formula C15H24O2, characterized by its molecular structure containing two t-butyl groups and a hydroxyl group attached to a phenyl ring. BHT is effective in preventing the oxidation of fats and oils, making it a common additive in food products, cosmetics, and pharmaceuticals to extend their shelf life and maintain quality. It is also used as a stabilizer in plastics and rubber, as well as an antioxidant in fuels and lubricants. Despite its benefits, BHT's safety has been a subject of debate, with some studies suggesting potential health risks, while others support its use within regulated limits.
The CAS Registry Mumber 732-29-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 2 respectively; the second part has 2 digits, 2 and 9 respectively. Calculate Digit Verification of CAS Registry Number 732-29: (5*7)+(4*3)+(3*2)+(2*2)+(1*9)=66 66 % 10 = 6 So 732-29-6 is a valid CAS Registry Number.
