Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- August 2022
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model, but not (completely) falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- Estimate calculation is adapted from Stein & Brown method, using US EPA EPISUITE Software.
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- Estimate calculation is adapted from Stein & Brown method.
- GLP compliance:
- no
- Boiling pt.:
- 438 °C
- Remarks on result:
- other: calculated using EPISUITE (v4.10)
- Conclusions:
- The estimated QSAR data was calculated using EPISUITE (v4.10). The boiling point of Dapsone (4,4’-DDS) was estimated to be 438 Deg C.
Reference
Description of key information
Value estimated by US EPA 2011 Estimation Programs Interface Suite™, v 4.10.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 438 °C
Additional information
EpiSuite estimation based on Stein & Brown method and Chemicalbook give both a boiling point value of 438 °C (no pressure specified)
