Applicant's summary and conclusion
- Conclusions:
- The test item Adenosine 5'-diphosphate monopotassium salt (dried) (CAS no. 70285-70-0) showed two exothermic effects starting at temperatures of 130 °C and 240 °C, respectively, with average energy releases of -460 J/g and -120 J/g.
- Executive summary:
The test item Adenosine 5'-diphosphate monopotassium salt (dried) (CAS no. 70285-70-0) showed two exothermic effects starting at temperatures of 130 °C and 240 °C, respectively, with average energy releases of -460 J/g and -120 J/g.
Due to the fact that the decomposition energy of the exothermic effects is greater than -300 J/g and the onset of the first exothermix effect started below 200 °C, self-reactive properties cannot be excluded.
Since the overall decomposition energy of the exothermic effects goes above the threshold of -500 J/g, explosive properties also cannot be excluded.
