Chemical Structure
Description
The occurrence of 5-(2-Bromoacetyl)thiophene-2-carboxylic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(2-Bromoacetyl)thiophene-2-carboxylic acid (CAS 96543-76-9), molecular formula C7H5BrO3S and molecular weight 249.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(2-Bromoacetyl)thiophene-2-carboxylic acid (C7H5BrO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
