Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Henry's Law constant: 0.102 Pa-m3/mole
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0.102
- at the temperature of:
- 25 °C
Additional information
The Henry's Law Constant (HLC) of ‘Esterification products of 1,3-dioxo-2-benzofuran-5-carboxylic acid with nonan-1-ol’, calculated using the EPA model HENRYWIN v3.20, is in the range:
HLC bond= (0.099 ÷ 0.231) Pa-m3/mole
HLC group= (0.052 ÷ 0.174) Pa-m3/mole
The key value is within the estimation range of the predicted HLC of the 15 principal components of the assessed UVCB substance.
This estimate is less accurate because that components are outside of the MW range of the training set compounds.
According to these results, the assessed UVCB substance appears slightly volatile from surface water.
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.
