West et al. (2008) provide an estimated water solubility of 6.8 mg/L at 25°C.
The test substance is covered by the category approach of
methylenediphenyl diisocyanates (MDI). Hence, data of the category
substances can be used to cover this endpoint. Any experimental
estimation of water solubility for MDI is questionable and therefore
QSAR may be considered. The West et al. (2008) study was an uptodate and
valid QSAR method (WSKOWWIN (v1.41) which is part of the Estimation
Program Interface (EPI) Suite, v3.20.) to provide a water solubility
value of 6.8 mg/L for 4,4'-MDI, which may be used for the CSA, although
it is only of theoretical value.
