Conclusions
The results of this experiment indicate that 3:2′-dimethyl-4-aminobiphenyl hydrochloride is unsuitable as a carcinogenic agent.
Possibly, future experiments with the free amine form in the pure state should be attempted, perhaps utilizing radioactive tagging of the carcinogen to determine the carcinogenic metabolite. Periodic chemical and biologic assay should be made of a carcinogenic agent to determine the presence of contaminants.
