2,6-Dichloro-3-(chlorosulfonyl)benzoic acid (CAS 53553-05-2) is a high-purity analytical reference standard with the molecular formula C7H3Cl3O4S and a molecular weight of 289.52 g/mol.
The molecular framework of 2,6-Dichloro-3-(chlorosulfonyl)benzoic acid (C7H3Cl3O4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
