3-Chloro-2-{[5-(4-fluorobenzenesulfonyl)thiophen-2-yl]methyl}-5-(trifluoromethyl)pyridine CAS 321430-97-1

Description

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.

3-Chloro-2-{[5-(4-fluorobenzenesulfonyl)thiophen-2-yl]methyl}-5-(trifluoromethyl)pyridine (CAS 321430-97-1) is a high-purity analytical reference standard with the molecular formula C17H10ClF4NO2S2 and a molecular weight of 435.84 g/mol.

Based on its molecular formula C17H10ClF4NO2S2, 3-Chloro-2-{[5-(4-fluorobenzenesulfonyl)thiophen-2-yl]methyl}-5-(trifluoromethyl)pyridine contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 435.84 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
