EC number: 229-194-7
CAS number: 6425-39-4
Examining the structural formula, the following observations can be made:
- The molecule does not contain any functional groups imparting
oxidising properties such as organic nitro compounds, N-halogen
compounds, oxohalogen compounds and interhalogen compounds.
- According to the two criteria quoted, oxidising properties can exist
- the electronegative atoms which are present constitute a high
proportion of the molecule and are bound to elements in a high oxidation
state -> in case of DMDEE the proportion of electronegative atoms in the
molecule is low (3 oxygen atoms out of an overall atom count of 41). All
oxygen atoms are bound to carbon atoms
- the electronegative atoms are bonded to each other or the other
electronegative elements such as iodine, nitrogen, sulphur or phosphorus
-> in case of DMDEE, the electronegative atoms are not bound to one
another, nor to any other electronegative elements.
Assessment against these two criteria indicates strongly that the
molecule will not have oxidising properties
In every respect of the oxidising liquids exemption procedure, DMDEE
does not show any evidence of possessing oxidising properties.
On the basis of this exercise, the substance should be considered as not
oxidising and should not be subjected to experimental testing.
The test substance was concluded from a GLP study not to have oxidising properties following a theoretical assessment of the chemical structure (Younis 2011).
The test substance does not need to be classified as an oxidising
substance as based on the chemical structure the substance does not
contain any chemical groups indicating oxidising properties.
