Any other information on results incl. tables

In the temperature range of 220 – 250 °C an endothermic effect can be observed, which is directly followed by an exothermic effect in the temperature range of 250 – 300 °C, with an average decomposition energy of -360 J/g. No further thermal effects could be observed up to the maximum test temperature of 500 °C.

Applicant's summary and conclusion

Conclusions:
The test item Adenosine (CAS no. 58-61-7) showed an endothermic effect in the temperature range of 220 – 250 °C, which is directly followed by a exothermic effect in the temperature range of 250 – 300 °C, with an average decomposition energy of -360 J/g.
Executive summary:

The test item Adenosine (CAS no. 58-61-7) showed an endothermic effect in the temperature range of 220 – 250 °C, which is directly followed by a exothermic effect in the temperature range of 250 – 300 °C, with an average decomposition energy of -360 J/g.
