Description of key information
The different handbooks and data sheets report a melting point range of
90 - 97 °C for p-chlorobenzonitrile.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 93.5 °C
Additional information
The reported melting point range for p-chlorobenzonitrile is reported to be 90 - 97 °C. Therefore, the approximated melting point of p-chlorobenzonitrile is 93.5 °C.
