Additional information

The value taken from the Merck Index (O'Neil 2006), a peer reviewed handbook which can be considered reliable and suitable for use as the key study for this endpoint. The supporting study (Yalkowsky and He 2003) is also a peer reviewed source and reports a water solubility of 79.99 mg/L at 25 ˚C and supports the value reported in the key study. The value used in the EU RAR (2004) for cyclohexane of 58 mg/L is also included as a supporting study.
