Key result

Parameter:

other: DSC: exothermal effect starting at 365 °C

Value:

207

Remarks on result:

other: exothermal effect starting at 365 °C with an energy of up to 207 J/g

The test item showed an exothermal effect starting at 365 °C with an energy of up to 207 J/g in closed DSC-measurements.

Two DSC measurements in closed flask crucibles showed an endothermal effect. Details are provided in the table below.

Ident-No.	Weight [mg]	Final temperature [°C]	Temperature range [°C]	Type of effect	Energy [J/g]
38917	11.10	500	210–235 365–435	Endothermal Exothermal	Not relevant 182
38925	12.05	500	200–230 370–440	Endothermal Exothermal	Not relevant 207

 

Interpretation of results:

GHS criteria not met

Conclusions:

The test item had no explosive properties in the sense of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Appendix 6: Screening Procedures.

Executive summary:

In a GLP study conducted according to OECD 113, a screening of explosive properties of the test item was performed. The test item showed an exothermal effect starting at 365 °C with an energy of up to 207 J/g in closed DSC measurements. As the heat of decomposition was below 500 J/g and due to the organic nature of the test item, the test item is not to be classified as a explosive substance in the sense of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Appendix 6: Screening Procedures.

Description of key information

N-(4-((4-(3-phenylureido)phenyl)sulfonyl)phenyl)benzenesulfonamide is not explosive.

Key value for chemical safety assessment

Explosiveness:
