(3,4-Difluorophenyl)(3-methanesulfonylphenyl)methanone CAS 1097139-98-4

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.

(3,4-Difluorophenyl)(3-methanesulfonylphenyl)methanone (CAS 1097139-98-4) is a high-purity analytical reference standard with the molecular formula C14H10F2O3S and a molecular weight of 296.29 g/mol.

Based on its molecular formula C14H10F2O3S, (3,4-Difluorophenyl)(3-methanesulfonylphenyl)methanone contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 296.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), (3,4-Difluorophenyl)(3-methanesulfonylphenyl)methanone 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.
