Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Justification for classification or non-classification

Classification for mutagenicity under Regulation 1272/2008 is warranted for substances which cause concern for humans owing to the possibility that they may induce heritable mutations in the germ cells of humans. The classification in Category 2 is based on:

— positive evidence obtained from experiments in mammals and/or in some cases from in vitro experiments, obtained from:

— somatic cell mutagenicity tests in vivo, in mammals; or

— other in vivo somatic cell genotoxicity tests which are supported by positive results from in vitro mutagenicity assays.

OECD 471 performed on analogue substance 4 showed clear negative results for all tested strain with and without Rat liver S9 metabolic activation system. The in-vivo test micronucleus performed on the analogue substance shows clear negativity. Based on these considerations and the read across assessment, the target substance is not considered mutagenic.
