- 2,3-Dihydro-1,3-dioxo-1H-perylo[3,4-cd]pyridine-8,9-dicarboxylic acid potassim salt (1:2)
- EC Number:
- 807-752-6
- Cas Number:
- 1451734-05-6
- Molecular formula:
- C24H9NO6K2
- IUPAC Name:
- 2,3-Dihydro-1,3-dioxo-1H-perylo[3,4-cd]pyridine-8,9-dicarboxylic acid potassim salt (1:2)
- Details on test material:
- It cannot be entirely excluded that the test material used was the mono potassium salt rather than the di potassium salt.
Constituent 1
- Specific details on test material used for the study:
- It cannot be entirely excluded that the test material used was the mono potassium salt rather than the di potassium salt. However, based on the very similar properties of these compounds, the toxicological data presented is considered valid and suitable to describe the toxicological property of the di potassium salt even if generated with the mono salt.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of this study the median lethal dose of the test substance after oral administration was found to be greater than 2,000 mg/kg body weight for the male and female animals.
- Executive summary:
An acute oral toxicity following OECD guideline 4223 and in compliance with GLP was performed to assess the test article's acute oral toxicity in Wistar rats. A single dose of 2000 mg/kg body weight of the test material preparation in doubly distilled water as given to six fasted animals (three males and three females) by gavage in sequential manner. No mortality occurred. No clinical signs and findings were observed. The mean body weìghts of the test groups increased throughout the study period. No macroscopic pathologic abnormalities were noted in the animals examined at the end of the observation period. Under the conditions of this study the median lethal dose of the test substance after oral administration was found to be greater than 2,000 mg/kg body weight for male and female rats.
