Applicant's summary and conclusion

Conclusions:
The vapour pressure is calculated to be below 0.00001 Pa.
Executive summary:

The vapour pressure of the non-ionised form of SND 919 Precursor 1 (Thiazol) at 20 °C was estimated to be 6.95 x 10-8 mm Hg corresponding to 9.3 x 10-6 Pa (using the Modified Grain method). The vapour pressure of the ionised form (hydrobromide) of SND 919 Precursor 1 (Thiazol) is considered to be distinctly below the estimated value of 9.3 x 10-6 Pa.

As the available experimental methods allow a determnatiopn of vapour pressure down to 10-5 Pa only, no meaningful experimental determination of the vapour pressure for SND 919 Precursor 1 (Thiazol) is possible. Therefore, in accordance to the respective EC guideline no experimental determinaion of the vapor pressure for SND 919 Precuror 1 (Thiazol) is required.
