In the temperature range used for vapour pressure measurements the test item was solid.
Vapour pressures were calculated using a molar mass of146.60 g/mol.
At the temperature applied the vapour pressure descended perpetually at constant temperature and reached the
identification limit of the most sensitive measurement technique.
Applicant's summary and conclusion
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.
