Description of key information

The water solubility of 3-methoxybutan-1-ol is 500 g/l. 

Key value for chemical safety assessment

Additional information

The new measurement in the manufacturer's test laboratory is considered reliable (Celanese, 2010). The result is suitable for use as the key study for this endpoint. The test result is "completely miscible in all ratios". In order to give a Key value it seems reasonable to enter 500 g/L as "plausible wildcard". This is supported by a value of 366.2 g/l calculated using WSKOWWIN (USEPA, 2008).
