Applicant's summary and conclusion

Conclusions:
The vapour pressure was determined at three temperatures and is reported as:

25°C (9.8E-7 - 5.2E-4 Pa) 60°C (3.8E-5 - 3.9E-3) and 95°C (7.3E-4 - 2.0E-2)
Executive summary:

The purpose of this study was to determine the vapour pressure of 937-688-5. The substance was tested using the isothermal TGA method according to the OECD 104 TG at three different temperatures - 25°C, 60°C and 90°C. Due to the complexity of the substance, the vapour pressures are reported as ranges:


25°C (9.8E-7 - 5.2E-4 Pa)


60°C (3.8E-5 - 3.9E-3 Pa)


95°C (7.3E-4 - 2.0E-2 Pa)
