Any other information on results incl. tables
Each reference substance was measured in duplicate by TGA using a temperature program that was specific for the substance. Plots of log vT obtained at elevated temperatures and 1/T were inter- or extrapolated to determine the log vT values at 20°C (log vT,20). The log vT values were plotted against the logarithm of the vapour pressure at 20°C in Pascal units (log PT, 20). Linear regression analysis using the least squares method yielded an equation of log PT,20 = 1.17 x log vT,20 + 4.75. The coefficient of correlation (r) was > 0.99. The constants c and d specific for the experimental arrangement were 1.17 and 4.75, respectively.

Results
In the range of 100°C and 130°C a log p versus 1/T curve for the test item could not be determined since the coefficient of correlation (r) was < 0.99 (data is archived in the raw data). From 170°C a non-linear weightless was observed. This was most likely due to reaction and/or decomposition of the test item.Since no accurate vapour pressure could be calculated from the obtained results the weight losses of the test item were compared with the results of hexachlorobenzene at the temperatures
of 100°C and 130°C.Since the weight loss of the test item was lower than the weight loss of the reference compound, the vapour pressure of the test item is considered to be below the vapour pressure of hexachlorobenzene. According to this the vapour pressure of the test item is given in the table below:
Vapour Pressure of the Test Item
| 20°C | 25°C | ||
| [Pa] | [mm Hg] | [Pa] | [mm Hg] |
Test item | < 1.5 ´ 10-3 | < 1.1 ´ 10-5 | < 4.3 ´ 10-3 | < 3.2 ´ 10-5 |
Applicant's summary and conclusion
- Conclusions:
- The isothermal TGA effusion method was applied for the determination of the vapour pressure of JNJ-73848242-AAA (T003901).
The vapour pressure of the test item at 20°C (293K) and 25°C (298K) was:
< 1.5 E-3 Pa or < 1.1 E-5 mmHg at 20°C, and
< 4.3 E -3 Pa or < 3.2 E-5 mmHg at 25°C
