Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Several independent literature data

Key value for chemical safety assessment

Relative density at 20C:
1.124

Additional information

The publication of Anschütz (1881) reports the synthesis of the submission item and gives data on the density of the material. Kloetzel (1948) investigated chemical reactions of nitroparaffins, one of them yielding the submission item. He confirmed the identity by elemental analysis and measured further the density at 20 °C. At the time of the publications no guideline existed and no data on the method applied are given, but the values were independently verified by several authors:

Due to the long-term use of the density information for confirmation of dimethyl itaconate identity together with other characteristics, sufficient weight of evidence is considered. The experiments are deemed valid, conclusive and thus suitable for assessment (reliable with restrictions, Klimisch score 2). The data are considered relevant and taken together adequate for the assessment of the relative density.

In result the experimentally determined relative density value is considered 1.124, i.e. ca. 12 % more dense than water.
