Chemical Structure

2,2-Difluoro-2-(fluorosulfonyl)acetic acid CAS 1717-59-5 chemical structure

Description

The occurrence of 2,2-Difluoro-2-(fluorosulfonyl)acetic acid is closely related to a sulfone group, a carboxylic acid group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,2-Difluoro-2-(fluorosulfonyl)acetic acid (CAS 1717-59-5), a certified reference material (molecular formula C2HF3O4S, MW 178.09 g/mol) for analytical method development and quality control.

Structurally, 2,2-Difluoro-2-(fluorosulfonyl)acetic acid (C2HF3O4S) contains a sulfone group, a carboxylic acid group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 178.09 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
