Interpretation of results:
toxic
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Substance is toxic in case of swallowing
Executive summary:

The acute oral toxicity of C5-Wittigesterchlorid/bromid was assessed in Wistar rats of both sexes, including a 14-day observation period.

After single dose administration (oral) of 400 mg/kg and 200 mg/kg of C5-Wittigesterchlorid/bromid 6/10 animals resp. 1/6 animals died within a few hours after dosing. The high-dose animals were sedated after treatment. Severe liver necrosis was observed at low- and high-dose. C5-Wittigesterchlorid/bromid is considered as "toxic in case of swallowing" according to the EEC guidelines.
