Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Physical & Chemical properties

Endpoint summary

Administrative data

Description of key information

Data for the physico-chemical properties were provided based on studies for the following endpoints: melting and boiling points, relative density, vapour pressure, partition coefficient, water solubility, flash point, auto-flammability and viscosity.

The results of the studies are reported in the endpoint summary as well as in the accompanying IUCLID database. Data for several endpoints were waived due to intrinsic properties or based on the criteria as laid down in regulation (EC) 1907/2008 Annex VII/IX column 2 or Annex XI.

The substance is a colourless limpid liquid at ambient temperature, with low volatility.

In water it is very slightly soluble, slightly less dense, with no surface-active properties. No dissociation of the parent compound is anticipated under environmental conditions.

The partition coefficient was estimated to be > 6.

It is NOT classified as dangerous with regard to physical hazards, based on CLP criteria.

It should be noted that slight variations of the properties could be observed within the purity or isomers composition range.
