CAS No.: 140-56-7
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.
