6,7-Difluoro-3-(phenylsulfonyl)quinolin-4(1H)-one CAS 899348-47-1

Description

6,7-Difluoro-3-(phenylsulfonyl)quinolin-4(1H)-one (CAS 899348-47-1) is a high-purity analytical reference standard with the molecular formula C15H9F2NO3S and a molecular weight of 321.30 g/mol.

Structurally, 6,7-Difluoro-3-(phenylsulfonyl)quinolin-4(1H)-one (C15H9F2NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, 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 321.30 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.

As a certified reference material (CRM), 6,7-Difluoro-3-(phenylsulfonyl)quinolin-4(1H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
