4,4'-Thiobis-phenol Usage And Synthesis
Chemical PropertiesWhite, crystalline powder.
Uses4,4'-thiobis-phenol can be applied to produce a non-halogen type epoxy (meth)acrylate resin having high refractive index, transparency and thermal stability. It is also used to produce a non-systemic organophosphorus insecticide TEMEPHOS.
UsesIntermediate, flame-retardant, antioxidant, engineering plastics.
DefinitionChEBI: 4,4'-thiodiphenol is a member of phenols. It derives from a hydride of a diphenyl sulfide.
