β-Hydroxyethyl-2,5-di-tert.-butyl-benzyl-sulfid, also known as 2,5-di-tert-butyl-benzyl-β-hydroxyethyl sulfide, is an organic compound with the chemical formula C16H28OS. It is a colorless to pale yellow liquid with a molecular weight of 268.46 g/mol. β-Hydroxyethyl-2,5-di-tert.-butyl-benzyl-sulfid is characterized by its unique structure, featuring a benzyl sulfide group with two tert-butyl substituents at the 2 and 5 positions, and a β-hydroxyethyl group attached to the sulfur atom. It is synthesized through the reaction of 2,5-di-tert-butylbenzyl chloride with sodium hydrosulfide, followed by the addition of ethylene oxide. β-Hydroxyethyl-2,5-di-tert.-butyl-benzyl-sulfid is primarily used as an intermediate in the production of antioxidants and stabilizers for polymers, particularly in the plastics and rubber industries, to prevent degradation and extend the lifespan of these materials.
The CAS Registry Mumber 22183-21-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,8 and 3 respectively; the second part has 2 digits, 2 and 1 respectively. Calculate Digit Verification of CAS Registry Number 22183-21: (7*2)+(6*2)+(5*1)+(4*8)+(3*3)+(2*2)+(1*1)=77 77 % 10 = 7 So 22183-21-7 is a valid CAS Registry Number.
