Description of key information
The melting point of the substance dimethylamine-borane (1:1) was evaluated in a weight-of-evidence approach using two literature references and one database entry. The melting point values obtained by these sources are in very good accordance and therefore sufficient for assessment of this endpoint. The mean melting point value is approximately 36 °C. The single values from the different sources are as follows:
- Levinskas J.G., 1955. Comparative Toxicity of Boranes: 35.5 - 36 °C;
- Noeth H. & Beyer H., 1960. Beiträge zur Chemie des Bors, I: Darstellung und Eigenschaften der Alkylamin-borane, R(3 -n)H(n)*BH3: 37 °C;
- Experimental value from SRC's PhysProp Database bundled with EPA's EpiSuite: 36 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 36 °C
