Benzenecarbothioamide, 3,5-bis(1,1-dimethylethyl)-4-hydroxy-N-phenyl-, also known as 4-hydroxy-3,5-di-tert-butylbenzenecarbothioamide, is a chemical compound with the molecular formula C17H23NOS. It is a white crystalline solid that is widely used as an antioxidant in the rubber and polymer industries. Benzenecarbothioamide,
3,5-bis(1,1-dimethylethyl)-4-hydroxy-N-phenyl- is particularly effective in preventing the oxidation of rubber, which can lead to degradation and loss of elasticity. It is also known for its ability to protect against ozone and heat-induced cracking, making it a valuable additive in the production of tires, hoses, and other rubber goods. The compound's chemical structure, with its hydroxyl group and phenyl ring, contributes to its antioxidant properties, and its di-tert-butyl groups provide steric hindrance, which can help to stabilize the molecule and enhance its performance in various applications.

853-98-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 853-98-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,5 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.Calculate Digit Verification of CAS Registry Number 853-98:
(5*8)+(4*5)+(3*3)+(2*9)+(1*8)=95
95 % 10 = 5
So 853-98-5 is a valid CAS Registry Number.
