Orthotolidine dihydrochloride
Orthotolidine dihydrochloride has been evaluated for
carcinogenicity by NTP. In drinking water studies, o-
tolidine dihydrochloride gave clear evidence for
carcinogenicity in both male and female rats and in
male mice. o-Tolidine, a structurally related compound,
is classified by IARC as a 2B Carcinogen (possibly
carcinogenic to humans), by NTP as a Group 2
Carcinogen (reasonably anticipated to be a carcinogen-
sufficient evidence from studies in experimental
animals), by ACGIH as an A2 Carcinogen (suspected
human carcinogen), and by NIOSH as a carcinogen
defined with no further categorization.
