4-tert-Butoxy-2,5-di-tert-butylphenol, also known as BHT or butylated hydroxytoluene, is a widely used synthetic antioxidant and preservative. It is a white crystalline solid with a molecular formula of C15H24O. BHT is commonly employed in the food industry to prevent oxidation and spoilage, as well as in the rubber, petroleum, and chemical industries to protect materials from degradation. The compound is characterized by its ability to scavenge free radicals, thereby inhibiting the oxidation process. It is also known for its low toxicity and is generally recognized as safe by regulatory bodies, although its use is regulated to ensure safety. BHT's chemical structure, with its phenolic hydroxyl group and tert-butyl groups, contributes to its stability and effectiveness as an antioxidant.
The CAS Registry Mumber 2460-80-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,6 and 0 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 2460-80: (6*2)+(5*4)+(4*6)+(3*0)+(2*8)+(1*0)=72 72 % 10 = 2 So 2460-80-2 is a valid CAS Registry Number.
