Description of key information
The vapour pressure of the test substance was determined with a guideline method (OECD TG 104, EU method A.4). The measured vapour pressure is 0.536 Pa at 20 °C. Within the range in which the vapour pressure was determined, 6% of the test substance had evaporated. Therefore the vapour pressure obtained derives only from the most volatile fraction.
Key value for chemical safety assessment

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.
