Endpoint summary
Administrative data
Description of key information
Nasal hemorrhage, sluggish locomotion and ruffled, unkempt coats were noted at 250 mg/kg. At dosage level of 500 mg/kg, 630 mg/kg and 800 mg/kg, the animals were lethargic with ruffled, unkempt coats. Spasmodic movements were noted. Within on hour, all animals were in a fetal position. Lacrimation, ocular and nasal hemorrhage were noted. Convulsions began approximately two hours after dosing. The animals dosed at 1000 mg/kg and 2000 mg/kg showed the same toxicity as at 800 mg/kg. All animals died within 2 -4 hours after incubation.
Key value for chemical safety assessment
Acute toxicity: via oral route

- Interpretation of results:
- Toxicity Category IV
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- LD50 value of the test item is 725 mg/kg (male albino rats), therefore the test item will be classified as acute toxic; category 4; oral, H302.
- Executive summary:
The study was performed 1976, before GLP- and OECD-testing guidelines were available and in force.
In this assay toxicity was recorded . LD50 value of the test item is 725 mg/kg (male albino rats), therefore the test item will be classified as
acute toxic; category 4; oral, H302 according to GHS/CLP classification criteria.
Reference
Nasal hemorrhage, sluggish locomotion and ruffled, unkempt coats were noted at 250 mg/kg. At dosage level of 500 mg/kg, 630 mg/kg and 800 mg/kg, the animals were lethargic with ruffled, unkempt coats. Spasmodic movements were noted. Within on hour, all animals were in a fetal position. Lacrimation, ocular and nasal hemorrhage were noted. Convulsions began approximately two hours after dosing. The animals dosed at 1000 mg/kg and 2000 mg/kg showed the same toxicity as at 800 mg/kg. All animals died within 2 -4 hours after incubation.
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed
- Dose descriptor:

Justification for classification or non-classification
The LD50 value of the test item is 725 mg/kg (male albino rats), therefore the test item will be classified as acute toxic; category 4; oral, H302.
