Scientific Review of 4,4'-Thiodianiline

CASRN 139-65-1
Status: Listed in the Report on Carcinogens (RoC)

Primary Uses or Exposures: 4,4'- Thiodianiline was used almost exclusively as a chemical intermediate in the production of three dyes: C.I. mordant yellow 16, milling red G, and milling red FR. However, only C.I. mordant yellow had any commercial significance in the United States; it was used to dye wool and for printing on wool, silk, and cotton. C.I. mordant yellow 16 has been used as an indicator in the United States government's nerve gas detector program.
