2-Ethyl-6-tert-butyl-4-methyl-phenol, also known as BHT or butylated hydroxytoluene, is a widely used synthetic antioxidant and preservative. It is an organic compound characterized by a phenol structure with an ethyl group at the 2-position, a tert-butyl group at the 6-position, and a methyl group at the 4-position. 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. It is also used as a stabilizer in plastics and rubber, as well as in gasoline to prevent engine knocking. 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 4560-36-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,6 and 0 respectively; the second part has 2 digits, 3 and 6 respectively. Calculate Digit Verification of CAS Registry Number 4560-36: (6*4)+(5*5)+(4*6)+(3*0)+(2*3)+(1*6)=85 85 % 10 = 5 So 4560-36-5 is a valid CAS Registry Number.
