Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data

Endpoint:
relative self-ignition temperature (solids)
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is a solid having a melting point <= 160°C
Justification for type of information:
The test item (CAS 604-68-2) has a melting range of 90.4 to 91.7°C at atmospheric pressure as determined by Differential scanning calorimetry. See further information in the cross-ref.

A first endothermic effect (double peak) could be observed in the temperature range of 85 - 120 °C (melting) and a second one in the temperature range of 270 – 370 °C.

During the heating phase a distinct endothermic effect was observed in the temperature range of 85 – 120 °C, which can be assigned to the melting of the test item. As the effect consists of a double signal and the onset temperatures in both tests deviate by more than 0.5 K from their mean value of 91.0 °C, the test item has a melting range from 90.4 to 91.7 °C.

Conclusions:
The test item Alpha-D-glucose pentaacetate (CAS no. 604-68-2) has a melting range of 90.4 to 91.7 °C at atmospheric pressure (1005 - 1007 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995).
Executive summary:

The test item Alpha-D-glucose pentaacetate (CAS no.604 -68 -2) has a melting range of 90.4 to 91.7 °C at atmospheric pressure (1005 - 1007 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995).
