EC number: 265-198-5 | CAS number: 64742-94-5 A complex combination of hydrocarbons obtained from distillation of aromatic streams. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C9 through C16 and boiling in the range of approximately 165°C to 290°C (330°F to 554°F).

Description of key information
The density of high purity DCPD is 0.9302 g/cm3 at 35°C. The density of commercial DCPD Is 975-989 kg/m3 at 20°C.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.98
Additional information
The CRC handbook is peer reviewed and is considered reliable and a suitable key study for this endpoint (Lide 2008). As a supporting study, WHO ICSC (2005) have identified the density of the test substance is 0.98 g/cm3. No information on the primary source of the data or the methods used is available. However, this information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use for this endpoint.
The density of commercial DCPD (94%) was taken from proprietary data (Shell 2016). The study is not GLP compliant but followed guideline ASTM D4052 and is considered suitable for use for this endpoint.
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.
