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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 208-011-4 | CAS number: 505-52-2
Endpoint summary
Administrative data
Key value for chemical safety assessment
Additional information
All three in vitro studies were GLP compliant and of high quality (Klimisch score:1) and were clearly negative. The results are acceptable for the human health risk assessment.
Justification for selection of genetic toxicity endpoint
All three studies were clearly negative so no key study was selected.
Short description of key information:
Gene mutation (Bacterial Reverse Mutation Assay/Ames test): the substance tridecanedioic acid (CAS No. 505-52-2) did not induce mutagenicity using S. typhimurium TA 98, TA 100, TA 1535, TA 1537 and TA 102 in the presence or absence of Aroclor 1254 –induced rat liver S9 metabolic activation (OECD 471, GLP);
Chromosome aberration (in vitro mammalian cell micronucleus test): the substance tridecanedioic acid (CAS No. 505-52-2) does not induce an increase in micronucleus frequencies in Chinese hamster ovary (CHO-K1) cells in the presence or absence of Aroclor 1254 –induced rat liver S9 metabolic activation (OECD 487, GLP);
Gene mutation (in vitro mammalian cell gene mutation): the substance tridecanedioic acid (CAS No. 505-52-2) does not induce gene mutations in mouse lymphoma L5178Y cells in the presence or absence of Aroclor 1254 induced rat liver S9 metabolic activation (OECD 476, GLP).
Endpoint Conclusion: No adverse effect observed (negative)
Justification for classification or non-classification
Based on the available information in the dossier, the substance tridecanedioic acid (CAS No. 505-52-2)
does not need to be classified for germ cell mutagenicity when the criteria outlined in Annex I of 1272/2008/EC are applied.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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
