Summary
The solubility of the potent drinking water mutagen 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX) in water (50.8, 44.7, 43.7, and 51.0 mg/ml at pH values 2, 5, 7, and 9, respectively) was only slightly dependent on pH, on the contrary to octanol/water partition (log Pow 1.13, 0.84, −0.44, and −1.02 at pH 2, 5, 7, and 9, respectively). MX was stable in ethyl acetate and acidic water solutions. The recovery of MX during isolation from water or urine samples was about 100% but about 73–82% in the methylation process. The alternative isolation and derivatization methods tested for MX did not give better results.
