Chemical compound

Tris(2,3-dibromopropyl) phosphate ("tris") is a chemical once widely used as a flame retardant in plastics and textiles.

Safety and regulation

Tris is mutagenic and listed as an IARC Group 2A carcinogen. It is one of the chemicals covered by the Rotterdam Convention. In the United States, the Consumer Product Safety Commission banned the sale of children's garments containing tris in 1977. This regulatory change came about as a result of the research of Bruce Ames and Arlene Blum.
