Air & Water Reactions
Sensitive to base hydrolysis and may spontaneously oxidize in solution. . Insoluble in water.
Reactivity Profile
4,4'-Thiobis(6-tert-butyl-m-cresol) may be sensitive to light.
Health Hazard
4,4'-Thiobis(6-tert-butyl-mcresol)
(TBBC) is of low systemic toxicity in
animals; allergic contact dermatitis has been
reported in humans.
Fire Hazard
4,4'-Thiobis(6-tert-butyl-m-cresol) is combustible.
Flammability and Explosibility
Nonflammable
Safety Profile
Poison by
intraperitoneal route and probably by
ingestion and inhalation. Mutation data
reported. See also SULFIDES. When heated
to decomposition it emits highly toxic fumes
of SOx.
Potential Exposure
This material is used as an antioxidant in the plastics and rubber industries; in Neoprene and other synthetic rubbers; in polyethylene and polypropylene.
Carcinogenicity
TBBC was not mutagenic in Salmonella
typhimurium strains with or without metabolic
activation. In Chinese hamster ovary cells,
TBBC induced an increase in sister chromatid
exchanges but there were no increases in chromosomal
aberrations.
Incompatibilities
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. May evolve explosive hydrogen sulfide upon contact with moisture or acids.
Check Digit Verification of cas no
The CAS Registry Mumber 96-69-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 96-69:
(4*9)+(3*6)+(2*6)+(1*9)=75
75 % 10 = 5
So 96-69-5 is a valid CAS Registry Number.

Paragraph 0033-0036, (2021/08/06)
The invention relates to a synthesis method of 4,4'-thiobis(6-tert-butyl-3-methylphenol). According to the method, chlorine and sulfur dichloride which are necessary to use in a traditional process are avoided, and a large amount of hydrogen chloride tail gas is not generated; a byproduct silver iodide and acid liquor are easy to recover and reuse, the environmental protection property and safety of the reaction are greatly improved, and the problems of equipment corrosion and the like are avoided. Therefore, the method is suitable for industrially synthesizing the 4,4'-thiobis(6-tert-butyl-3-methylphenol).
