Additional information

Reasonably consistent values are available from multiple sources, including values at different temperatures. The key parameter retained is from values measured at elevated temperatures using a national guideline method with extrapolation to ambient temperature. This value is 0.5Pa at 25C. Clearly this substance has very low volatility.
