Key value for chemical safety assessment

Vapour pressure:
14 000 Pa
at the temperature of:
25 °C

Additional information

A predicted vapour pressure of 14000 Pa at 25°C was determined for the substance using a validated QSAR estimation method. The result is considered to be reliable and selected as key study. This is supported by vapour pressures of 13000 Pa at 25°C, 13500 at 20°C and 34500 Pa at 50°C reported for the substance in secondary sources to which reliability could not be assigned. A

measured vapour pressure of 25000 Pa at 25°C using a method similar to static method of OECD 104 was determined for the substance. However, the reliability is unassignable because an accuracy of ±2 -3 pounds/sq inch (approximately 14000 - 21000 Pa) was reported and there was no information on the purity of the test substance.

The supporting studies were in agreement with the key study that the vapour pressure of the substance is >10,000 Pa at 25°C.
