- study cannot be used for classification
- Remarks:
- Migrated information
- Executive summary:
Rats (strain not specified; 5/sex/dose; fasted) were administered “Unamide CDX” via gavage at doses of 1000, 2000, 4000, 8000, 16,000 or 32,000 mg/kg and observed for 14 days. The robust summary identified this compound as CASRN 68140-00-1, although no information on the composition of Unamide CDX, or the percent or purity of the CASRN 68140-00-1 in this compound, was provided. Mortality was observed in groups administered > 8000 mg/kg: 3/5 at 8000 mg/kg, 5/5 at 16,000 mg/kg and at 32,000 mg/kg. The robust summary does not specify if these results apply to both males and females, although it is presumed that it does not (since the numerator is 5, rather than 10, and because the robust summary states that test substance was
“equally toxic” to males and females.)
LD50 = 7400 mg/kg
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.
