(Difluoromethyl)bis(2,5-dimethylphenyl)sulfonium tetrafluoroborate CAS 2133476-51-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (Difluoromethyl)bis(2,5-dimethylphenyl)sulfonium tetrafluoroborate.

CATO supplies (Difluoromethyl)bis(2,5-dimethylphenyl)sulfonium tetrafluoroborate (CAS 2133476-51-2), a certified reference material (molecular formula C17H19F2SBF4, MW 380.20 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, fluorine substitution, an aromatic ring system, (Difluoromethyl)bis(2,5-dimethylphenyl)sulfonium tetrafluoroborate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 380.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
