Description of key information
2-Ethylbutyric acid has a reported melting point / freezing point between -31.8 and 15.24 °C. Given the disparity in results, the most conservative value obtained from experimental data is recommended: -15 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -15 °C
