Chemical Structure
Description
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.
Methyl 2-((2,6-difluorophenyl)sulfonyl)acetate (CAS 1325304-66-2), molecular formula C9H8F2O4S and molecular weight 250.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 2-((2,6-difluorophenyl)sulfonyl)acetate (C9H8F2O4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures Methyl 2-((2,6-difluorophenyl)sulfonyl)acetate 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.
