Test material
Constituent 1
- Specific details on test material used for the study:
- Read across data is presented from the structurally related substance, 1,1'-Bis(ferrocenyl)octane, CAS Number 501410-94-2, EC Number 479-710-1. This substance bears a close structural similarity to 1,1"-isopropylidenebis(ethylferrocene), CAS Number 37206 -42 -1, EC Number 310 -202 -3, the distinction being that the alkyl bridging functionality between the two ferrocene moieties is an octyl derivative as opposed to an isopropyl derivative and that two cyclopentadienyl moieties in the target substance bear ethyl substituents.

- Mortality:
- Female: 2000 mg/kg bw; Number of animals: 6; Number of deaths: 0
- Clinical signs:
- Signs of toxicity related to dose levels: Clinical signs noted at 2000 mg/kg dose level were: slight or moderate activity decrease, hunchback posture, piloerection and respiration rate increase. These signs disappeared within 2 days after administration of the test item.
- Gross pathology:
- Effects on organs: No effects on mean body weight and body weight development were noted. Specific macroscopic alterations linked to the toxic effect of the test item 1,1'-Bis(ferrocenyl)octan have not been observed.
Applicant's summary and conclusion
- Interpretation of results:
- Category 5 based on GHS criteria
- Conclusions:
- According to OECD 423, 1,1'-Bis(ferrocenyl)octan has an acute oral LD50 >2000mg/L. This was the dose limit in the experiment and therefore is also the LD0.
- Executive summary:
The acute oral toxicity of 1,1'-Bis(ferrocenyl)octane, CAS Number 501410-94-2, EC Number 479-710-1was investigated in accordance with the standardised guideline OECD 423.
An OECD 423 study conducted to GLP in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results was performed on 1,1'-Bis(ferrocenyl)octane, CAS Number 501410-94-2, EC Number 479-710-1.
The study was assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).
This substance is considered to be sufficiently close in structural integrity to 1,1"-isopropylidenebis(ethylferrocene), CAS Number 37206 -42 -1, EC Number 310 -202 -3 so as to justify valid read across.
Under the conditions of the study 1,1'-Bis(ferrocenyl)octan has an acute oral LD50 >2000mg/L. This was the dose limit in the experiment and therefore is also the LD0.
