[Preparation of Rubber Accelerator Tetramethyl Thiuram
In the study, rubber accelerator tetramethyl thiuram monosulfide (TMTM) was synthesized firstly. Single crystal TMTM was cultivated by solvent evaporation method. TMTM was detected and characterized by XRD single crystal diffraction, FTIR, TG-DSC. The micro-structure and intrinsic regularity were revealed.

Allergy to rubber accelerators | DermNet NZ
Allergy to rubber accelerators is diagnosed by the clinical history and by special allergy tests, patch tests. These tests may identify which specific rubber accelerators you have an allergy to. Thiuram mix tests four thiuram chemicals with one test. One of these four will cause about 9 out of 10 cases of allergy to thiuram mix.

Thiuram disulfide
Thiuram disulfides are weak oxidant. They can be reduced to dithiocarbamates. Treatment of thiuram disulfides with triphenylphosphine or cyanide salts gives the thiuram sulfide: (R 2 NCSS) 2 + PPh 3 → (R 2 NCS) 2 S + SPPh 3 Applications. The tetramethyl derivative, known as thiram, is a widely used fungicide.
