Sodium 3,5-difluorobenzenesulfinate CAS 1233509-85-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium 3,5-difluorobenzenesulfinate.

CATO supplies Sodium 3,5-difluorobenzenesulfinate (CAS 1233509-85-7), a certified reference material (molecular formula C6H3F2O2SNa, MW 200.13 g/mol) for analytical method development and quality control.

The molecular framework of Sodium 3,5-difluorobenzenesulfinate (C6H3F2O2SNa) 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
