Trisulfide, bis[4-(1,1-dimethylethyl)phenyl], also known as 4,4'-Di-tert-butylbenzene-1,2,3-trisulfide, is an organic compound with the chemical formula C18H26S3. It is a colorless to pale yellow solid that is insoluble in water but soluble in organic solvents. Trisulfide, bis[4-(1,1-dimethylethyl)phenyl] is primarily used as an antioxidant and a vulcanization accelerator in the rubber industry, enhancing the strength and durability of rubber products. It is also employed as a stabilizer in various polymers to prevent degradation caused by heat, light, and oxygen exposure. Due to its chemical structure, it is effective in scavenging free radicals and preventing the oxidation of polymer chains, thus extending the lifespan of materials.

13846-49-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13846-49-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,4 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13846-49:
(7*1)+(6*3)+(5*8)+(4*4)+(3*6)+(2*4)+(1*9)=116
116 % 10 = 6
So 13846-49-6 is a valid CAS Registry Number.

A simple method to prepare unsymmetrical di- tri- and tetrasulfides

Derbesy, Gerard,Harpp, David N.

, p. 5381 - 5384 (2007/10/02)

Unsymmetrical di- tri- and tetrasulfides can be prepared in a one-pot reaction using SO2Cl2 SCl2 and S2Cl2 respectively to permit coupling of the appropriate thiols.

Desulfurization of Organic Trisulfides by Tris(dialkylamino)phosphines. Mechanistic Aspects

Harpp, David N.,Ash, David K.,Smith, Roger A.

, p. 5155 - 5160 (2007/10/02)

Tris(dialkylamino)phosphines effect a rapid desulfurization of trisulfides to disulfides under mild conditions.The reaction mechanism involves a bimolecular process, proceeding by the rate-determining formation of a phosphonium salt intermediate.The central sulfur atom of a diaryl trisulfide is removed in the process, while a dialkyl trisulfide loses a terminal sulfur atom to the aminophosphine.
