Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-52 °C

Additional information

Experimental data is available for this endpoint.

Polynt (2009) report a melting point for diisobutyl phthalate of -52°C. This is used as a key study for this endpoint.

Woodward (1988) reports that the melting point of -50°C and a pour point of -37°C. IPCS (2006) reports a singular melting value of -37°C. Both of these are used as supporting studies.
