OECD SIDS o-<strong>TOLUIDINE</strong><br />

5. TOXICITY ID: <strong>95</strong>-<strong>53</strong>-4<br />

DATE: 07.01.2005<br />

---In the present work the compound with code no 41 is declared as otoluidine<br />

hydrochloride, whereas in an the overall summary of this program<br />

code no. 41 is declared as o-toluidine.<br />

METABOLIC ACTIVATION:<br />

S9 mix - liver homogenates from with Aroclor 1254 induced male Sprague-<br />

Dawley rats<br />

Three concentrations of S9-mix were used to test compounds that gave<br />

negative results (0.05, 0.1, and 0.3 ml of S9/ml of mix).<br />

Reliability : (4) not assignable<br />

Method-Evaluation, only three strains tested, only four concentrations<br />

tested, unclear use: o-toluidine or o-toluidine hydrochloride<br />

15.07.2004 (152) (188)<br />

Type : Ames test<br />

System of testing : Salmonella typhimurium TA 100, TA 1<strong>53</strong>5, TA 1<strong>53</strong>8<br />

Test concentration : 1, 2, 3, 4, 5 µmol/plate<br />

Cycotoxic concentr. : no data<br />

Metabolic activation : with and without<br />

Result : negative<br />

Method : other: according to Ames et al., Mutat. Res. 31, 347 (1975)<br />

Year : 1979<br />

GLP : no data<br />

Test substance : other TS: o-toluidine, purified by destillation<br />

Result : o-toluidine was inactive in all tested strains with or without activation by rat<br />

liver homogenate<br />

Test condition : METABOLIC ACTIVATION:<br />

S9 mix liver homogenates from Aroclor 1254 induced male Fischer 344<br />

rats<br />

POSITIVE CONTROLS:<br />

N-methyl-N´-nitro-N-nitrosoguandine<br />

picrolonic acid<br />

chrysene<br />

quinoline<br />

CONCENTRATIONS/VEHICLE<br />

Various concentrations of test compound in 50µl of DMSO were added to<br />

0.1 ml of an overnight nutrient broth culture of the bacterial tester strain.<br />

Reliability : (4) not assignable<br />

3 strains only, documentation insufficient for assessment<br />

15.07.2004 (189)<br />

Type : Ames test<br />

System of testing : Salmonella typhimurium TA 98, TA 100<br />

Test concentration : data not given<br />

Cycotoxic concentr. :<br />

Metabolic activation : with and without<br />

Result : negative<br />

Method : other: according to Ames et al., Mutat. Res. 31, 347 (1975)<br />

Year : 1987<br />

GLP : no data<br />

Test substance : other TS: o-toluidine, no data on purity<br />

Result : o-toluidine was non-mutagenic in presence or absence of rat liver S9 in<br />

TA100 and TA98<br />

data of positive controls not shown<br />

Test condition : METABOLIC ACTIVATION:<br />

S9 mix liver homogenates from Aroclor 1254 induced male albino rats<br />
