3,4-Dimethyl-6-(1,1,2-trimethyl-propyl)-phenol, also known as 6-tert-butyl-3,4-dimethylphenol or BHT, is a synthetic phenolic compound commonly used as an antioxidant and preservative. It is a white crystalline solid with a molecular formula of C15H24O and a molecular weight of 220.35 g/mol. BHT is widely used in the food, pharmaceutical, and chemical industries to prevent oxidation and spoilage, extending the shelf life of products. It is also employed as a stabilizer in plastics and rubber, as well as an intermediate in the synthesis of other chemicals. Due to its antioxidant properties, BHT helps protect against the formation of free radicals, which can cause damage to cells and contribute to aging and various diseases. However, its use has been a subject of debate due to potential health concerns, and it is regulated in different countries with varying limits on its application.
The CAS Registry Mumber 4934-70-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,3 and 4 respectively; the second part has 2 digits, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 4934-70: (6*4)+(5*9)+(4*3)+(3*4)+(2*7)+(1*0)=107 107 % 10 = 7 So 4934-70-7 is a valid CAS Registry Number.
