Colour: light blue (turquoise) - Key result
- Melting / freezing pt.:
- ca. 287 °C
- Decomposition:
- yes
- Decomp. temp.:
- ca. 287 °C

- Executive summary:
In a study according to Guideline OECD 102 employing the capillary method, copper monoglycinate sulfate dihydrate underwent melting upon decomposition at the temperature given below. Thereby no liquid state was obtained. Upon decomposition the colour promptly darkens from blue to grey and finally black.
Melting point: 287 ± 1.5 °C with decomposition
Reference
The test item underwent melting upon decomposition at the temperature given below. Thereby no liquid state was obtained. Upon decomposition the colour promptly darkens from blue to grey and finally black.
Melting point: 287 ± 1.5 °C (with decomposition)
The same final value given above (287 °C) was obtained in two independent melting point determination runs.
Description of key information
The test substance underwent melting with decomposition at 287 ± 1.5 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 287 °C
Additional information
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.
