Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Boiling point
Administrative data
Link to relevant study record(s)
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:-
| Source | Boiling Point / °C | Reference |
| CRC Handbook of Chemistry and Physics | 210 | CRC Handbook |
| Sigmal Aldrich library of chemical safety data. | 209 - 210 | Sigmal Aldrich library of safety data |
| International Program on Chemical Safety | 210 | International Chemical Safety card for 2,4 -Dichlorophenol |
| OECD SIDS Initial Assessment Report | >= 209 — <= 210 | SIDS |
| OECD SIDS Initial Assessment Report | >= 209 — <= 211 | SIDS |
| OECD SIDS Initial Assessment Report | 210 | SIDS |
| OECD SIDS Initial Assessment Report | >= 207 — <= 209 | SIDS |
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
