Notes: N,N'-Diphenyl-1,4-phenylenediamine (DPPD) is a p-phenylenediamine and non-oxidized version of DPPD-Q (Item No. 40826). It is toxic to the aquatic bacterium V. fischeri (EC50 = 0.02 mg/L).{72316} DPPD (10 µg/L) reduces the viability of HepG2 hepatocellular carcinoma cells.{68747} It decreases urinary protein levels and serum levels of bilirubin in male rats when administered at a dose of 100 mg/kg per day.{72384} DPPD (50 and 300 mg/kg per day) increases the time in gestation for female rats when administered to pregnant dams.
