Additional information

The CRC Handbook is a peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint. The supporting study (ICSC 2003) is also a peer reviewed handbook and supports the value reported in the key study, giving a vapour pressure of 10 kPa at 20˚C.
