Description
Compared with other compounds in its class, the molecular weight of 452.50 g/mol gives 3-(1-((2-Fluoro-[1,1'-biphenyl]-4-yl)oxy)ethyl)-1-((4-methoxyphenyl)sulfonyl)-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(1-((2-Fluoro-[1,1'-biphenyl]-4-yl)oxy)ethyl)-1-((4-methoxyphenyl)sulfonyl)-1H-pyrazole (CAS 477709-12-9) is a high-purity analytical reference standard with the molecular formula C24H21FN2O4S and a molecular weight of 452.50 g/mol.
Based on its molecular formula C24H21FN2O4S, 3-(1-((2-Fluoro-[1,1'-biphenyl]-4-yl)oxy)ethyl)-1-((4-methoxyphenyl)sulfonyl)-1H-pyrazole contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 452.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
