Description of key information

4.38E-17 Pa at 25°C
(calculated)

Key value for chemical safety assessment

Additional information

- The calculation of vapour pressure was using modified Grain method.

- As the test substance has a high molecular weight (621g/mol) the vapour pressure would expected to be lower 1 Pa. Based on OECD Guideline in the lowest vapour pressure range is recommended using Gas saturation method and isothermal Thermogravimetry method. For both methods the measuring temperature range 120 -150°C is required. Since the test substance has a melting range 100-144°C thus it is technically not possible to conduct the study.
