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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Executive summary:
Method
The test has been conducted according to EU method A.3. No other information on method is available; available data derived from migrated NONS file, as per Article 25(3) request, with permission to refer granted by ECHA.
Results
Relative density: 1.71.
Referenceopen allclose all
The result is a mean of 2 determinations.
Description of key information
Relative density between 1 and 2 at 20 °C.
Key value for chemical safety assessment
Additional information
No data on test substance itself was available. A weight of evidence approach was adopted, using Similar Substance 01 and 02 as read across substances. In particular, Similar Substance 01 is an isomer of test substance, differing only for the position of one functional group on an aromatic ring; Similar Substance 02 has structural similarity with test susbtance. A detailed justification of the read across process is attached in section 13.
Based on migrated information from NONS file, as per Article 25(3) request, Similar Substance 01 has relative density of 1.71 at 20 °C. Permission to refer is granted by ECHA.
As for Similar Substance 02, relative density was found to be 1.81 at 20 °C.
Overall, based on available data, relative density of test item is expected to be between 1 and 2.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
