EC number: 221-070-0
CAS number: 2997-92-4
- Safety pre-test 1: When heated on a
magnesia groove over a Bunsen burner, the test substance fizzled with
white smoke, melted to a yellow-brown liquid and burned with a yellow
flame. When the test item was beaten with a hammer on the anvil, the
test substance was compacted, no reaction was observed.
- Safety pre-test 2: The outside gold seal
was grey-black discoloured and slightly bulged after reaching a
temperature of 520 °C. After cooling, weight was recorded as 621.42 mg.
When the crucible was opened, the test substance was charred, the gold
seal was grey-black discoloured and
- After calibration with indium and zinc
the measurement of indium yielded the values shown in Figure 1 and Table
3.3-a (attached). The measurement of indium after calibration met the
- The DSC curve for the test item is shown
in Figure 2 (attached).
- The DSC values for the test item are
shown in Table 3.4-a (attached).
- Mass of the test item: 1.04 mg
- Mass of crucible before measurement:
- Mass of crucible after measurement:
- Observations: After the test the
crucible was visually unchanged, the crucible was opened and the gold
seal and the test item were discoloured black/grey.
Thermal stability of the test item was
investigated by conducting a DSC (differential scanning calorimetry)
screening test from 0 °C to 520 °C.
During the DSC run an exothermal event
caused by decomposition was observed at the temperature of 164.50 °C
(onset) and this was integrated to derive the related energy (in J/g).
The related energy of the observed exothermal event was 597.41 J/g.
