Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

RS-Freetext:
Die Versuchs- und Kontrollgruppen bestanden aus je 10 - 12
Tieren.
In der hoechsten Dosierung starben 75 % der Muttertiere, 
bei den restlichen 25 % konnte keine Traechtigkeit mehr
festgestellt werden. In der 100 mg/kg Dosisgruppe war die
maternale Koerpergewichtsentwicklung signifikant 
reduziert. Der Prozentsatz lebender Foeten und der der
Foetenmortalitaet entsprachen der Kontrolle. Das
Foetengewicht in der 100 mg/kg Dosisgruppe war signifikant
reduziert. Die Zahl der Foeten mit Missbildungen war
gegenueber der Kontrolle nicht erhoeht, jedoch wurde bei 
den Foeten eine allgemeine Retardierung in der Entwicklung
festgestellt. In der 50 mg/kg Dosisgruppe wurde weder
maternale Toxizitaet noch eine embryo-/foetotoxische oder
teratogene Wirkung festgestellt.
