Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Toxicity to reproduction
Administrative data
- Endpoint:
- extended one-generation reproductive toxicity - with F2 generation and developmental neurotoxicity (Cohorts 1A, 1B with extension, 2A and 2B)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- pending (please refer to attached justification)
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- study ongoing
- Justification for type of information:
- In the Final Decision on a Testing Proposal dated 10 December 2018, ECHA requested to submit a Pre-natal developmental toxicity study (Annex IX, Section 8.7.2.; test method: OECD TG 414) in a first species (rat or rabbit) via oral route and an Extended one-generation reproductive toxicity study (Annex IX, Section 8.7.3.; test method: OECD TG 443) in rats via oral route with the registered substance by 17 June 2021. However, due to several reasons as lined out in the letter from the performing laboratory, the experimental phase of these studies has been delayed.
Please refer to the attached documents for further details regarding the request of the ECHA Final Decision.
