Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Testing of the stability of the substance in organic solvents is not considered critical and hence not proposed.
Additional information
According to column 1 of Annex IX (EU REACH), testing is required only if the stability of the substance is considered to be critical. Testing of the stability of the substance in organic solvents is not considered critical for the following reasons: 1) the substance does not contain organic solvents as manufactured. 2) the substance is not diluted or stored in organic solvents prior to use. 3) where relevant, checks on the stability of standards of the test substance in organic solvents is confirmed as part of routine analytical protocols to ensure confidence in study results. For instance, in the octanol-water partition coefficient, a stability test for the stock solutions of the substance in octanol were conducted as part of this test. The high substance recoveries obtained show that there had been no significant degradation of the stock solutions, in terms of concentration over the test period , and hence the n-octanol solutions used in the test were considered to have been stable for the duration of the test. Based on the above arguments, no separate stability test in organic solvents is considered necessary or proposed.
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.
