Chemical Structure
Description
Based on its molecular formula C5H3BrClNO2SHCl, 6-Bromopyridine-3-sulfonyl chloride hydrochloride contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 292.96 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).
