Chemical Structure
Description
The molecular framework of 5-Bromo-2-nitrothiophene-3-carbaldehyde oxime (C5H3BrN2O3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
5-Bromo-2-nitrothiophene-3-carbaldehyde oxime (CAS 1201924-03-9) is a high-purity analytical reference standard with the molecular formula C5H3BrN2O3S and a molecular weight of 251.06 g/mol.
