Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2,4-Dichlorophenyl)-2-methoxy-5-(phenylthio)furan.
3-(2,4-Dichlorophenyl)-2-methoxy-5-(phenylthio)furan (CAS 941270-41-3) is a high-purity analytical reference standard with the molecular formula C17H12Cl2O2S and a molecular weight of 351.25 g/mol.
Based on its molecular formula C17H12Cl2O2S, 3-(2,4-Dichlorophenyl)-2-methoxy-5-(phenylthio)furan contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 351.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
