Thermal Stability (OECD 113)
In the DSC runs PN18271 and PN18272, the test item showed an endothermic effect starting at a temperature of approx. 240 °C, which can be assigned to the melting of the test item (see Section 4.2 Melting point). The endothermic effect was directly followed by an exothermic effect starting at a temperature of 250 °C, with an average decomposition energy of -1060 J/g. No further thermal effects could be observed up to the maximum test temperature of 500 °C.
The results of the DSC measurements are summarized in a table:

Energies of exothermic effects are presented in the table as negative values and energies of endothermic effects as positive values.
Explosive properties UN Class 1
The DSC measurements in closed crucibles showed a decomposition of the test item with an maximum decomposition energy of -1140 J/g, meaning the decomposition energy goes beyond the threshold of -500 J/g to exclude explosive properties.
Due to the fact that the decomposition energy is above the threshold of -500 J/g the Koenen and the Time Pressure test had to be performed.
Due to the fact that the decomposition energy goes above the threshold of -800 J/g also the Trauzl Test had to be performed.
Explosive Properties; Thermal Sensitivity: Koenen Test
One series of three tests with a 1.0 mm diameter orifice plate were performed.
Results of the Koenen Test are presented in the table below:

Due to the fact that the test series with anorifice plate diameter of 1.0 mm showed no explosionthe UN-Transport Regulation Test 1(b) and 2(b) is deemed to be “-“.

Due to the fact that the test item did not reach a pressure of 2070 kPa, the UN-Transport Regulation Test 1(c)(i) and 2(c)(i) deemed to be “-“.
Explosive Properties; Trauzl Test
One test with a test item mass of 4.85 g was carried out. Thevolume of the enlarged cavity is 4.0 mL. The normalization to 10 g of the test item results in an expansion of 8.3 mL per 10 g. Due to the fact that the normalized expansion was above 8 mL per 10 g test item, a second testwith a test item mass of 5.10 g was carried out for verification. Thevolume of the enlarged cavity of the second test is 4.0 mL. The normalization to 10 g of the test item results in an expansion of 7.8 mL per 10 g.
Due to this result, the UN-Transport Regulation Test F.3 results in to be “No”. Based on this the UN-Transport Regulation Test 1(a) and 2(a) is deemed to be “-“.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- According to the results of the tests on explosive properties (UN Transport Regulation, Test series 1 and 2), the test item does not have to be classified as explosive substance in class 1 according to the UN Transport Regulation nor as explosive substance according to GHS or CLP Regulation EC 1272/2008 Annex 1: 2.1.
- Executive summary:
Thermal Stability (OECD 113)
The test item 5-Amino-2-nitrobenzoic acid (CAS no. 13280-60-9) showed an endothermic effect starting at a temperature of approx. 240 °C, which can be assigned to the melting of the test item (see report CSL-19-1030.01). The endothermic effect was directly followed by an exothermic effect starting at a temperature of 250 °C, with an average decomposition energy of -1060 J/g.
Explosive Properties UN Class 1:
In the DSC measurement the energy of the exothermic decomposition of the test item
5-Amino-2-nitrobenzoicacid (CAS no. 13280-60-9) was > -500 J/g. Therefore, further tests on explosive properties had to be performed.In the tests on explosive properties according to UN Transport Regulation, Test series 1 and 2, the test item showed no explosive properties.
According to the results of the tests on explosive properties, the following conclusion can be drawn:
UN Transport Regulation: The test item does not have to be classified as explosive substance in class 1 according to the UN Transport Regulation.
GHS (CLP Regulation EC 1272/2008: Annex 1: 2.1): The test item does not have to be classified as explosive substance according to GHS or CLP Regulation EC 1272/2008 Annex 1: 2.1, respectively.
