Description of key information
Henry´s Law constant: 23 Pa m3/mol derived with the formula in ECHA Guidance R.16.

Additional information
The Henry´s Law constant was derived with the formula given in the ECHA Guidance from 2016 (Guidance on information requirements and Chemical Safety Assessment, Chapter R.16: Environmental exposure assessment). This value was based on the measured values for vapour pressure (4280 Pa), molecular weight (102 g/mol) and water solubility (19000 mg/L) of the test substance. The Henry´s Law constant was calculated as 23.0 Pa m3/mol.
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.
