6-tert.-Butyl-4-tert.-octyl-2-tert.-butoxy-phenol, 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 C22H34O. BHT is commonly added to food products, cosmetics, and pharmaceuticals to prevent oxidation and extend shelf life. It works by donating hydrogen atoms to free radicals, thereby stabilizing them and preventing further oxidation. While BHT is generally considered safe for consumption in regulated amounts, there is ongoing debate about its potential health effects, and some countries have restricted its use in certain applications.

2555-81-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2555-81-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,5 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.Calculate Digit Verification of CAS Registry Number 2555-81:
(6*2)+(5*5)+(4*5)+(3*5)+(2*8)+(1*1)=89
89 % 10 = 9
So 2555-81-9 is a valid CAS Registry Number.
