An endothermic effect was observed between 25°C and 125°C followed by a
broad endothermic effect starting at 150°C. The endothermic effect was
most likely obtained due to melting of the test item. The second
endothermic effect was probably obtained due to reaction and/or
decomposition of the test item.
After the experiment, a dark brown molten residue remained in the sample
container (original colour: white to slightly yellow). The change of the
colour indicated reaction and/or decomposition of the test item. Based
on this visual observation, it was found that the test item had molten
and the change of the colour demonstrated reaction and/or decomposition
of the test item.
The boiling temperature of D-Ribose was tested by DSC according to OECD
103 guideline study.
Reaction and/or decomposition of the test item was observed during DSC
experiment at temperatures of > 150°C (> 423K). Boiling of the test item
was not observed below the temperature at which reaction and/or
