Chemical Structure
Description
Potassium 4-chlorobenzenesulfonate (CAS 78135-07-6), molecular formula C6H4ClO3SK and molecular weight 230.70 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Potassium 4-chlorobenzenesulfonate (C6H4ClO3SK) is characterized by a salt form, 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. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Potassium 4-chlorobenzenesulfonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
