Lot: 17-064163-4
- Expiration date of the lot/batch: 20 March 2019
-Purity test date: 25 September 2017
Appearance: Light grey powder
Storage conditions: Room temperature, keep container tightly closed - Key result
- Melting / freezing pt.:
- > 400 °C
- Remarks on result:
- other: No melting observed up to 400°C
- Conclusions:
- The test item Lithium salicylate has no melting point up a temperature of 400 °C as determined by differential scanning calorimetry and capillary method at atmospheric pressure.
- Executive summary:
The test itemLithiumsalicylatehas nomelting point up a temperature of 400 °Cas determined by differential scanning calorimetry and capillary method according to Regulation EC No. 440/2008 Method A.1., OECD Test Guideline 102 (1995).
Reference
To verify the results of the DSC measurement, three additional measurements with the capillary method (Apparatus:Stuart Melting PointSMP30) were performed in the temperature range of 25 – 400 °C with a heating rate of 10 K/min. According to the observations during the test with the capillary method, the first endothermic effect in the temperature range of 120 – 320°C in the DSC measurements cannot be assigned to the melting of the test item, since the test item does not melt optically. The test item changed its colour from white to brown starting at a temperature of approx. 360 °C. No melting of the test item observed up to a temperature of 400 °C.
Description of key information
The test item Lithium salicylate has no melting point up a temperature of 400 °C as determined by differential scanning calorimetry and capillary method according to Regulation EC No. 440/2008 Method A.1., OECD Test Guideline 102 (1995).
Key value for chemical safety assessment
Additional information
Since the study was GLP compliant and followed the aforementioned guidelines, the study was given a reliability rating of 1 (reliable without restrictions).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
