- Key result
- Operating temp.:
- <= 500 °C
- Remarks on result:
- other: The test item showed in the investigated temperature range up to 500 °C no exothermic effects. The test item was black after the DSC-measurement.
- Conclusions:
- The thermal stability of the test item N,N’-di-L-alanyl-L-cystine / (L-Ala-L-Cys)2 was investigated according to OECD Test Guideline 113 (1981). The DSC-measurements showed a first endothermic effect in the temperature range of 190 – 230 °C. A second endothermic effect was detected in the temperature range of 310 – 370 °C. The test item showed in the investigated temperature range up to 500 °C no exothermic effects. The test item was black after the DSC-measurement.

Description of key information
no exothermic effects up to 500 °C (OECD 113, GLP)
Additional information
The thermal stability of the test item N,N’-di-L-alanyl-L-cystine / (L-Ala-L-Cys)2 was investigated according to OECD Test Guideline 113 (1981). The DSC-measurements showed a first endothermic effect in the temperature range of 190 – 230 °C. A second endothermic effect was detected in the temperature range of 310 – 370 °C. The test item showed in the investigated temperature range up to 500 °C no exothermic effects. The test item was black after the DSC-measurement.
Justification for classification or non-classification
The available data indicate that the substance does not fulfil the classification criteria for self-reactive substances and mixtures in accordance with Regulation (EC) No. 1272/2008 (CLP) and the Globally Harmonized System for Classification and Labelling (GHS).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
