Additional information

Acute oral toxicity was tested in a study, where 20 rats and 20 mice received a single oral application of 200 -3200 mg/kg bw of the test substance 2-chlorobenzaldehyde. After dosing, observations were recorded for 14 days. Because deaths as well as clinical signs of toxicity were observed in both species, the LD50 for acute oral toxicity was estimated as 2160 mg/kg bw for rats and 1900 mg/kg bw for mice.

Justification for selection of acute toxicity – oral endpoint
Comparable to current guideline requirements and scientifically valid with acceptable restrictions.

Justification for classification or non-classification

Due to the effect levels obtained in the acute oral toxicity studie, a classification into Cat. 4 according to EU and GHS criteria is required.
