Key result

Sample tested:

other: based on the structural formula of the test substance

Remarks:

statement by expert under GLP conditions

Parameter:

other: groups associated with oxidising properties, eletronegative atoms bound to high proportions bound to high oxidation state and electonegative atoms bonded to electronegative elements

Remarks on result:

other: the structural formula does not contain any of the parameters mentioned above

Remarks:

based on its structural formula

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 when:

- the electronegative atoms which are present constitute a high proportion of the molecule and are bound to elements in a high oxidation state -> In the case of the test substance there are no highly electronegative atoms.

- the electronegative atoms are bonded to each other or the other electronegative elements such as iodine, nitrogen, sulphur or phosphorus -> In the case of the test substance there are no highly electronegative atoms.

Assessment against these two criteria indicates strongly that the molecule will not have oxidising properties

In every respect of the oxidising liquids exemption procedure, the test substance 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.

Interpretation of results:

GHS criteria not met

Conclusions:

The substance is concluded not to have oxidising properties. The substance meets all criteria for exemption from testing and has a structure not at all conducive with that required to exhibit oxidising tendencies.

Description of key information

The test substance was concluded from a GLP-compliant study not to have oxidising properties following a theoretical assessment of the chemical structure (Younis, 2012).

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Justification for classification or non-classification

The test substance needs not to be classified as an oxidising substance as based on the chemical structure the substance does not contain any chemical groups indicating oxidising properties.
