Description of key information
The substance is poorly biodegradable.
Key value for chemical safety assessment
Additional information
Test on the biodegradability of CAS 17852-98-1 are not available. However three tests on structural analogue substances indicate that the substance is poorly biodegradable.
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).
In a guideline study following OECD guideline 301 C and GLP on CAS 73612-29-0 a degradation rate of 0 % based on O2 consumption of the inoculum was determined (Dainippon Ink and Chemicals Inc., 2006). In a second test conducted in compliance with OECD guideline 301B and GLP on CAS 7023-61-2 the CO2 evolution of activated sludge inoculation time was recorded. The substance was degraded by 0 % during 28 days inoculation time (RCC Ltd, 2007). In a study according to OECD guideline 301C the biodegradability of CAS 5281-04-9 was tested. The substance was inoculated with a mixture of sewage, soil and natural water and the O2 consumption during 28 days inoculation time was recorded. Overall the substance was degraded by 9 -12 % after 28 days (JETOC, 1992). The substances are composed of an analogue organic part that is laked with different metals. Due to the characteristics of the bonding a disintegration of the molecule at environmentally relevant pH is not expected.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
