Our method describes the quantification in mouse urine of trimethylamine (TMA), trimethylamine N-oxide (TMAO) and creatinine. The method combines derivatization of TMA, with ethyl bromoacetate, and LC chromatographic separation on an ACE C18 column. The effluent was continuously electrosprayed into the linear ion trap mass spectrometer (LTQ), which operated in selective ion monitoring (SIM) mod...
In the title compound, C(8)H(10)N(2)O(3), the hydrazinecarboxyl-ate group is twisted from the furan ring by 6.98 (17)°. In the crystal, the mol-ecules are linked into one-dimensional chains running along the c axis by N-H⋯O hydrogen bonds.
In the title compound, C(12)H(12)O(4), the dihedral angle between the plane through the phenyl ring and the mean plane of the side chain is approximately 14°. The mol-ecules, which contain an intra-molecular O-H⋯O hydrogen bond, are linked end-to-end by weak C-H⋯O inter-molecular hydrogen-bonding contacts, forming infinite one-dimensional chain systems in the crystal structure.
