WHO: 1-Bromopropane and Dimethylformamide Suspected of Being Carcinogens

Experts from more than eight different countries recently came together in the International Agency for Research on Cancer (IARC), an entity of the World Health Organization (WHO), in Lyon to assess the cancer risk of seven chemical substances:

  • 2-Mercaptobenzothiazole
  • Dimethylformamide
  • Hydrazine
  • Tetrabromobisphenol A
  • 1-Brompropane
  • 3-Chloro-2-Methylpropene, technical grade
  • Dimethyl-p-toluidine

The results will be published in the next monograph, Volume 115.

Agencies have increasingly focused on 1-Brompropane. Among other uses, the substance is employed as an industrial solvent for steam degreasing, in spray adhesives, and in dry cleaning. In the United States, the EPA considers the compound carcinogenic when workers are exposed to it regularly and in great amounts, as the case with spraying applications.

The substance is currently undergoing assessment according to the requirements of the Toxic Substances Control Act (TSCA). If the assessment confirms the potential hazards exists, the agency will take the appropriate measures.

The REACH Regulation lists 1-Brompropane among substances of very high concern (SVHC). Environmental law in California (California Proposition 65) also considers the substance carcinogenic.
