Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
Physico-chemical properties of the substance were obtained from literature sources (mainly handbooks). Some endpoints were waived, based on chemical structure.
The substance is a liquid at ambient temperature, with high volatility.
In water, it is moderately soluble, much less dense, with no surface-active properties anticipated (i.e. excess will floate, then evaporate rapidly).
It has low potential for bioaccumulation and aquatic chronic toxicity, based on CLP criteria.
It is classified as an EXTREMELY FLAMMABLE LIQUID, based on CLP criteria.
