Chemical Structure
Description
The occurrence of 2-Formylphenyl 4-chlorobenzenesulfonate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Formylphenyl 4-chlorobenzenesulfonate (CAS 634593-06-9), molecular formula C13H9ClO4S and molecular weight 296.73 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Formylphenyl 4-chlorobenzenesulfonate (C13H9ClO4S) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 2-Formylphenyl 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.
