Rationale for the classification
1 Explosives *
-
-
- - There is a chemical group associated with explosive properties (N-oxides) present in the molecule, and the calculated oxygen balance is -125, higher than the criteria: -200, but the classification is not possible due to no data.
2 Flammable gases *
-
-
- - Solid (GHS definition). It was classified as "Not classified (Not applicable)."
3 Aerosols *
-
-
- - Not aerosol products. It was classified as "Not classified (Not applicable)."
4 Oxidizing gases *
-
-
- - Solid (GHS definition). It was classified as "Not classified (Not applicable)."
5 Gases under pressure *
-
-
- - Solid (GHS definition). It was classified as "Not classified (Not applicable)."
6 Flammable liquids *
-
-
- - Solid (GHS definition). It was classified as "Not classified (Not applicable)."
7 Flammable solids *
-
-
- - No data available.
8 Self-reactive substances and mixtures *
-
-
- - There is a chemical group associated with explosive properties (N-oxides) present in the molecule, but the classification is not possible due to no data.
9 Pyrophoric liquids *
-
-
- - Solid (GHS definition). It was classified as "Not classified (Not applicable)."
10 Pyrophoric solids *
-
-
- - No data available.
11 Self-heating substances and mixtures *
-
-
- - No data available.
12 Substances and mixtures which, in contact with water, emit flammable gases *
-
-
- - The chemical structure of the substance does not contain metals or metalloids (B, Si, P, Ge, As, Se, Sn, Sb, Te, Bi, Po, At). It was classified as "Not classified (Not applicable)."
13 Oxidizing liquids *
-
-
- - Solid (GHS definition). It was classified as "Not classified (Not applicable)."
14 Oxidizing solids *
-
-
- - The substance is an organic compound containing chlorine and oxygen (but not fluorine), and the oxygen is chemically bonded to an element (N) other than carbon or hydrogen. However, the classification is not possible due to no data.
15 Organic peroxides *
-
-
- - Organic compounds containing no bivalent -O-O- structure in the molecule. It was classified as "Not classified (Not applicable)."
16 Corrosive to metals *
-
-
- - Classification is not possible because test methods applicable to solid substances are not available.
17 Desensitized explosives *
-
-
- - There are no chemical groups associated with explosive properties present in the molecule. It was classified as "Not classified."
