Endpoint summary
Administrative data
Description of key information
The acute oral LD50 in rats is between 1100 and 1450 mg/kg bw and the acute dermal LD50 in rabbits is mg/kg bw.approximately 3000 mg/kg bw.
Key value for chemical safety assessment
Acute toxicity: via oral route
Endpoint conclusion
- Dose descriptor:
- LD50
- Value:
- 1 100 mg/kg bw
Acute toxicity: via dermal route
Endpoint conclusion
- Dose descriptor:
- LD50
- Value:
- 3 000 mg/kg bw
Additional information
The acute oral LD50 in rats is between 1100 and 1450 mg/kg bw. 3-Cyanopyridine as tested in male rabbits has an acute dermal LD50 of approximately 2.0 gm/kg, and an acute dermal LD50 of between 2.0 gm/kg and 4.0 gm/kg for female rabbits. The consensus value is 3000 mg/kg.
Justification for classification or non-classification
An acute oral LD50 between 1100 and 1450 mg/kg bw places this substance in oral Category IV according to Regulation (EC) No. 1272/2008. As the acute dermal LD50 is over 2000 mg/kg bw, it is not classified.
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.
