Description of key information

The references included regarding boiling point report a boiling range of 207 - 211 degrees C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
210 °C

Additional information

The endpoints presented represent four study references, the fourth of which is from the SIDS (Screening Information Data Set) dossier which, in itself, includes four reported boiling point values. The results from the endpoints are summarised in the table below:-

All references report a boiling point of either 210 or 209 - 211 degrees C with one lower range of 207 -209 degress C. It is possible that in this case the material was less pure resulting in a larger boiling range although the purity profile of the substance sample is not reported. In addition to this the boiling point of 2,4 -dichlorophenol is reported to be 210 degrees C in the "Community Right to know List". Therefore, the majority of reported values are in agreement in that the boiling point of 2,4 -Dichlorophenol is 210 degrees C.

It is therefore concluded that the boiling point of 2,4 -dichlorophenol is 210 degrees C.
