Description
CATO manufactures 4-Formyl-2-methoxyphenyl 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.
4-Formyl-2-methoxyphenyl 4-chlorobenzenesulfonate (CAS 432009-49-9), molecular formula C14H11ClO5S and molecular weight 326.75 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Formyl-2-methoxyphenyl 4-chlorobenzenesulfonate (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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
