Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Key result
Melting / freezing pt.:
217.5 °C
Conclusions:
The substance has a melting point of 217.5°C.
Endpoint:
melting point/freezing point
Type of information:
(Q)SAR
Adequacy of study:
other information
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with limited documentation / justification
Qualifier:
equivalent or similar to guideline
Guideline:
other: ECHA guidance on information requirements and chemical safety assessment Chapter R.6: QSARs and grouping of chemicals.
Specific details on test material used for the study:
Since (Q)SAR models are not applicable to salts, the predicion was carried out for Diacerin acid and extrapolated to Diacerin potassium.
Key result
Melting / freezing pt.:
ca. 244 °C
Remarks on result:
other: Result by Consensus method

The result appears reliable with restrictions as the predicted compound could be out of the applicability domain of the model.

Conclusions:
The substance has a melting point of ca. 244°C.

Description of key information
