Description

Compared with other compounds in its class, the molecular weight of 338.42 g/mol gives 2-(4-Isopropylphenyl)-6-phenyl-4H-thiopyran-4-one 1,1-dioxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(4-Isopropylphenyl)-6-phenyl-4H-thiopyran-4-one 1,1-dioxide (CAS 174493-23-3), a certified reference material (molecular formula C20H18O3S, MW 338.42 g/mol) for analytical method development and quality control.

Based on its molecular formula C20H18O3S, 2-(4-Isopropylphenyl)-6-phenyl-4H-thiopyran-4-one 1,1-dioxide contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 338.42 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.

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.
