Description

Compared with other compounds in its class, the molecular weight of 404.71 g/mol gives 4-(3,5-Bis(trifluoromethyl)phenoxy)benzenesulfonylchloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(3,5-Bis(trifluoromethyl)phenoxy)benzenesulfonylchloride (CAS 885950-90-3) is a high-purity analytical reference standard with the molecular formula C14H7ClF6O3S and a molecular weight of 404.71 g/mol.

Based on its molecular formula C14H7ClF6O3S, 4-(3,5-Bis(trifluoromethyl)phenoxy)benzenesulfonylchloride contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 404.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
