Results and discussion
Henry's Law constant H
- H:
- 0 Pa m³/mol
- Remarks on result:
- other: calculated using measured VP of 0.000049 Pa and solubility of 568 g/L
Applicant's summary and conclusion
- Conclusions:
- 1.295E-08 Pa*m3/mol estimated by calculation
- Executive summary:
A Henry's Law constant of 1.295E-08 Pa*m3/mol was calculated for the test substance from measured vapour pressure (0.000049 Pa) and solubility (568 g/L) values and molecular weight (150.13 g/mol) using EQUATION R.16-4 (Henry = (VP*MW)/Solubility) in the REACH guidance R.16.
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.
