- Executive summary:
The explosive properties of the test material were conducted in a study performed to the standardized guideline EU Test Method A.14., under GLP conditions. The explosive properties assessment has been based on the provided structural information only and information on the original materials used for preparation. The provided structure does not have any explosophores associated with its structure. As the test substance has variable composition with variable amounts of oxygen and sulphur the oxygen balance was calculated for the range of different numbers of oxygen and sulphur atoms based on the most likely molecular formulas. The mean calculated oxygen balance ranged from -214.14 to -211.53%. These values are all below -200% which would not suggest explosive properties. Based on the theoretical structural assessment and the DSC analysis, the test substance is not considered to have explosive properties.
Reference
Differential Scanning Calorimetry
The DSC analysis gave two exotherms; the onset temperatures were 328 and 537°C respectively and energies of 270 and 788 J/g. The second exotherm was >500 J/g, but due to it being very broad is unlikely to indicate explosive properties, especially when the structural considerations discussed below are taken into account.
Oxygen Balance
It should be noted that the test substance has a variable amount of oxygen and sulfur . The explosive properties assessment has been based on the provided structural information only and information on the original materials used for preparation.
The provided structure does not have any explosophores associated with its structure.
As the test substance has variable composition with variable amount of oxygen and sulphur the oxygen balance was calculated for the range of different numbers of oxygen and sulphur atoms based on the most likely molecular formulas. The mean calculated oxygen balance ranged from -214.14(for C54H108Mo2N2 P2O3S5) to –211.53% (for C54H108Mo2N2 P2OS7). These values are all below -200% which would not suggest explosive properties. Based on the theoretical structural assessment and the DSC analysis, the test substance is not considered to have explosive properties.
