Chem. Abstr. Name: 4-[(Dimethylamino)phenyl]diazene sulfonic acid, sodium salt

5. Summary of Data Reported and Evaluation

5.1 Animal carcinogenicity data

Contradictory results were obtained in two studies in which para-dimethylaminobenzenediazo sodium sulfonate was given orally to rats. The experiment suggesting hepatocarcinogenicity was inadequately reported, while the experiment suggesting lack of hepatocarcinogenicity was of too short duration. Therefore, no evaluation can be made.

5.2 Human carcinogenicity data

No case reports or epidemiological studies were available to the Working Group.

Subsequent evaluation: Suppl. 7 (1987) (p. 62: Group 3)

For definition of Groups, see Preamble Evaluation.
