1-((4-Fluorophenyl)thio)-3-methylbutan-2-one CAS 1481243-09-7

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.

1-((4-Fluorophenyl)thio)-3-methylbutan-2-one (CAS 1481243-09-7) is a high-purity analytical reference standard with the molecular formula C11H13FOS and a molecular weight of 212.28 g/mol.

Based on its molecular formula C11H13FOS, 1-((4-Fluorophenyl)thio)-3-methylbutan-2-one contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 212.28 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.

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.
