Key value for chemical safety assessment

Additional information

In the acute oral toxicity test, no mortality was seen at a dose of 2000 mg/kg. Body weight gain was normal and no abnormalities were seen on macroscopic examination.

In the acute inhalation study, animals were exposed to 20.6 mg/l for four hours. No mortality occurred and no clinical signs were noted. Macroscopic evaluation did not show any abnormalities and body weight gain was normal.
