Any other information on results incl. tables
The vapour pressure was measured in the temperature range of 53 to 78 °C. The measured vapour pressure values together with the measured temperatures are given in the table in the next section "overall remarks".
Due to the fact that the test item showed no proper linear correlation of the vapour pressure and the inverse temperature 1/T, the Antoine constants cannot be evaluated in the measured temperature range. Therefore,the vapour pressure will be estimated according to the measured vapour pressures.
Applicant's summary and conclusion
- Conclusions:
- The test item Nicotinamide-beta-D-riboside bromide (CAS no. 78687-39-5) showed no evaluable vapour pressure curve in the temperature range of 53 to 78 °C. Due to this result, the vapour pressures for the temperatures 20, 25 and 50 °C are estimated on the basis of the maximum measured vapour pressures, according to Regulation EC No. 440/2008 Method A.4. and OECD Test Guideline 104 (2006). The vapour pressure of the test item was <1.7 × 10-3 Pa at 20°C, <1.7 × 10-3 Pa at 25°C and <1.7 × 10-3 Pa at 50°C.
- Executive summary:
The test item Nicotinamide-beta-D-riboside bromide (CAS no. 78687-39-5) showed no evaluable vapour pressure curve in the temperature range of 53 to 78 °C. Due to this result, the vapour pressures for the temperatures 20, 25 and 50 °C are estimated on the basis of the maximum measured vapour pressures, according to Regulation EC No. 440/2008 Method A.4.and OECD Test Guideline 104 (2006):
