Reference
The results of the tests on the determination of the density of the test substance are given in the following table. The individual measurements were obtained with an accuracy of < 0.01 g/cm3. According to the guideline, the density of the test substance is given as the mean value.

Additional information
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.
