3-(3,4-Difluorophenyl)-4-(4-Methylsulfonylphenyl)-5H-Furan-2-One CAS 162011-83-8

Description

The occurrence of 3-(3,4-Difluorophenyl)-4-(4-Methylsulfonylphenyl)-5H-Furan-2-One is closely related to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(3,4-Difluorophenyl)-4-(4-Methylsulfonylphenyl)-5H-Furan-2-One (CAS 162011-83-8), molecular formula C17H12F2O4S and molecular weight 350.34 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-(3,4-Difluorophenyl)-4-(4-Methylsulfonylphenyl)-5H-Furan-2-One (C17H12F2O4S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 350.34 g/mol, it falls into the moderately-high-molecular-weight range. 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.
