- Adequacy of study:
- key study
- Study period:
- 14 Jul - 01 Aug 2014
- Reliability:
- 1 (reliable without restriction)

- Qualifier:
- according to guideline
- Guideline:

- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7220 (Boiling Point / Boiling Range)
- Deviations:
- not applicable
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- not applicable
- GLP compliance:
- yes
- Type of method:
- differential scanning calorimetry
- Boiling pt.:
- 249 °C
- Atm. press.:
- 1 014 hPa
- Decomposition:
- no
- Conclusions:
- A boiling point of 249 °C at 1014 hPa was observed for C4 sulfonamido methacrylate as determined by the OECD 103 method.
- Executive summary:
The boiling point of C4 sulfonamido methacrylate was tested using differential scanning calorimetry (DSC) in four experiments. The boiling temperature was determined as the mean evaporation temperature of three trials done under comparable conditions. The study was conducted in accordance with the OECD 103 method and was GLP compliant; therefore the study is considered reliable without restrictions.
Reference
Four trials were conducted. In all cases, the test substance had evaporated from the test chamber. The DSC-curves obtained during the four experiments are included in the attachments. Extrapolated onset temperatures for trials 1, 2, and 4 were 248.10 °C, 248.66 °C, and 248.89 °C. A repeated heating cycle was applied in Experiment 2. In Experiment 3, a closed sample container was used. The extrapolated onset temperature of the evaporation peak was 305.72 °C. This shift to a higher temperature in a closed container demonstrates that evaporation of the test substance is the reason for the endothermic effect.
Description of key information

Key value for chemical safety assessment
Additional information
In the key study, the boiling point of C4 sulfonamido methacrylate was tested using differential scanning calorimetry (DSC) in four experiments. The boiling temperature was determined as the mean evaporation temperature of three trials done under comparable conditions. The study was conducted in accordance with the OECD 103 method and was GLP compliant; therefore the study is considered reliable without restrictions.
