Applicant's summary and conclusion

Conclusions:
The vapour pressure of the test item Reaction mass of glycyl-L-tyrosine hydrochloride and potassium chloride was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C, according to Regulation
EC No. 440/2008 Method A.4. Vapour Pressure and OECD Test Guideline No. 104 (2006).

Temperature / °C Vapour pressure / Pa
20 5.9 ×10-7
25 1.2 ×10-6
50 3.1 ×10-5
