Chemical Structure

4-Chloro-2,5-difluorobenzenesulfinic acid sodium salt CAS 1233506-31-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 234.58 g/mol gives 4-Chloro-2,5-difluorobenzenesulfinic acid sodium salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Chloro-2,5-difluorobenzenesulfinic acid sodium salt (CAS 1233506-31-4), a certified reference material (molecular formula C6H2ClF2O2SNa, MW 234.58 g/mol) for analytical method development and quality control.

Structurally, 4-Chloro-2,5-difluorobenzenesulfinic acid sodium salt (C6H2ClF2O2SNa) contains a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 234.58 g/mol, it falls into the medium-molecular-weight range. 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.
