The title mol-ecular salt, C5H6N3O2 (+) ·H2NO3S(-), was obtained from the reaction of sulfamic acid with 2-amino-5-nitro-pyridine. A proton transfer from sulfamic acid to the pyridine N atom occurred, resulting in the formation of a salt. As expected, this protonation leads to the widening of the C-N-C angle of the pyridine ring, to 122.9 (3)°, with the pyridinium ring being essentially planar ...

Simulated sunlight irradiation causing degradation of amidosulfuron, a pyrimidinylsulfonylurea herbicide, has been investigated in aqueous solution. The main degradation products were followed up by ultrahigh-pressure liquid chromatography with a UV detector (UHPLC-UV) and identified by combining ultrahigh-pressure liquid chromatography-mass spectrometry (UHPLC-MS) and Fourier transform ion cyc...

Regioselective sulfamoylation of primary hydroxyl groups enabled a 5-step synthesis (overall yield 17%) of the first reported small molecule inhibitor of sulfatase-1 and 2, ((2S,3R,4R,5S,6R)-4,5-dihydroxy-2-methoxy-6-((sulfamoyloxy)methyl)tetrahydro-2H-pyran-3-yl)sulfamic acid, which obviated the use of hydroxyl protecting groups and is a marked improvement on the reported 9-step synthesis (ove...
