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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
- experimental determiantion and calculation were not possible due to the extremely low solubilities in water and octanol.
- logPow= 2.2 at 25°C at pH ca. 7
(value of the similar substance)
Key value for chemical safety assessment
Additional information
The test substance was insoluble in water and in n-octanol therefore it is not possible to determine the logPow experimentally and also the calculation using software will be generated too high logPow value which is unreliable. As the solubilities of both solvents were below the limit of detection (10 ppb) thus the logPow value of the substance is expected to be low.
As worst-case the logPow value has been provided by the similar substance.
Justification for read-across to the structural analogue substance with CAS number 1047-16-1 referred to ECHA disseminated dossier
The substance being registered differs from the analogue substance corresponds to CAS 1047-16-1 just by plus 2 oxygen atoms bonding to the bezene ring in the center. Further the water solubility of the analogue substance was stated to be 10.3 µg/L which is consisdered close to the substance being registered.
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.
