Specific details on test material used for the study:

SOURCE OF TEST MATERIAL
- Name of the test material (as cited in study report): Tellurium diethyldithiocarbamate
- Batch No.: 60700109
- Expiration date of the lot/batch: 10-07-2018
- Purity: 99.19% (HPLC)
- Appearance: Light orange to yellow powder

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
The test item was stored in a tightly closed vessel at room temperature (15.8 – 21.5 °C) under dry conditions in the dark.

Decomposition:

yes

Remarks:

during the melting process

Decomp. temp.:

> 138 - < 180 °C

Remarks on result:

not determinable

Remarks:

substance decomposed before boiling

At 116 °C the test item started to melt at into red-brown liquid. At 138 °C the test item was completely melted. At 180 °C the test item boiled (observation at the surface). After cooling down the test item was like gel and the colour stayed red-brown. The test item decomposed during melting process and the study was termintated. No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid.

Description of key information

No boiling point could be determined as the substance decomposed before boiling.
