Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term toxicity to aquatic invertebrates
Administrative data

Description of key information
With high probability acutely not harmful to aquatic invertebrates. No acute toxic effects occur within the range of solubility.
Key value for chemical safety assessment
Additional information
Data on acute toxicity to aquatic invertebrates using CAS 17852-98-1 are not available.
However, studies on the acute toxicity to daphnids are available for five different analogue substances.
In general, the analogue substances are composed of a structurally analogue organic part laked with different metals (Ca2+, Sr2 +, Ba2 +, Mn2+). Due to the laking a disintegration of the molecule at pH values relevant in the environment is not expected. Thus an effect or a release of the metal part is not likely. Therefore a transfer of the results obtained for structural related substances to CAS 17852-98-1 is feasible (see Annex).
The acute toxicity of CAS 5280-66-0, 7585-41-3, CAS 7023-61-2, CAS 5281-04-9 and CAS 73612-29-0 to Daphnia magna was tested in five different guideline studies following OECD guideline 202 and GLP. A static test system was set up in all five studies. All studies used saturated solutions and detected an EC50 > 100 mg/l respectively showed no acute toxicity within the range of solubility after an exposure period of 48 hours (BASF AG 2000, BASF AG 2001a, 2001b, RCC Ltd 2007, Kurume Laboratory 2005).
In overall conclusion, the test substance is with high probability acutely not harmful to aquatic invertebrates.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
