4-tert-Butoxy-2-tert-octyl-phenol, also known as BHT or butylated hydroxytoluene, is a widely used synthetic antioxidant and preservative. It is an organic compound with the molecular formula C20H30O. BHT is a colorless to pale yellow crystalline solid that is insoluble in water but soluble in organic solvents. It is commonly used in the food industry to prevent oxidation and spoilage, as well as in the rubber, petroleum, and chemical industries to protect materials from degradation. BHT is also found in various consumer products, including cosmetics, pharmaceuticals, and animal feed. Its antioxidant properties help to extend the shelf life of products and maintain their quality. However, there has been some debate regarding its safety, with some studies suggesting potential health risks, while others support its use as a safe and effective preservative.
The CAS Registry Mumber 2460-86-8 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 6 respectively. Calculate Digit Verification of CAS Registry Number 2460-86: (6*2)+(5*4)+(4*6)+(3*0)+(2*8)+(1*6)=78 78 % 10 = 8 So 2460-86-8 is a valid CAS Registry Number.
