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

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

DATE: 07.01.2005<br />

Test condition : This study is part of a International Collaborative Program, published as:<br />

Evaluation of Short-Term Tests for Cancerogens Progress in Mutation<br />

Research Vol 1. Edited by Frederick J. Serres and John Ashby, 1981<br />

CHEMICALS:<br />

42 coded chemicals were investigated in short-term tests for<br />

cancerogenicity in different laboratories<br />

It should be suggested that only 100%-pure chemicals should be used<br />

when evaluating a test system.<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 />

Doses: ½, ¼, 1/8 LD50 (0.388 mg/kg). Sampling 6 hours after last<br />

application<br />
