Chemical Structure
Description
Based on its molecular formula C4H4BrNOS, (4-Bromoisothiazol-5-yl)methanol contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 194.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
