Description of key information
Orientating Oral (Rat, comparable to OECD TG 401): LD50 > 5 g/kg
[Schering AG, Report No. 4954, 1984-01-24]
Key value for chemical safety assessment
Additional information
In an orientating toxicity study the single oral administration of the test substance (ZK 74.804) to male rats at doses of 0.25, 0.5, 1.0, 2.0, 3.5 and 5 g/kg was tolerated without any mortality or compound-related macroscopic pathological signs. Main clinical findings were spastic gait and ruffled fur which were observed on the first day after application in all dose groups. From day 2 onwards all animals were without findings.
The acute oral toxicity of AD-Cyanhydrin in rats is therefore above 5 g/kg body weight.Justification for classification or non-classification
Based on the study results a classification according to Directive 67/548/EEC and Regulation (EC) No. 1272/2008 (CLP) is not required.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
