Chemical Structure
Description
2-Chloro-4-formyl-6-methoxyphenyl benzenesulfonate (CAS 443664-40-2), molecular formula C14H11ClO5S and molecular weight 326.75 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloro-4-formyl-6-methoxyphenyl benzenesulfonate (C14H11ClO5S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic 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 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-Chloro-4-formyl-6-methoxyphenyl benzenesulfonate 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.
