2-[(3,4-difluorophenyl)sulfanyl]-2-phenylacetic acid CAS 1097125-23-9

Description

Compared with other compounds in its class, the molecular weight of 280.29 g/mol gives 2-[(3,4-difluorophenyl)sulfanyl]-2-phenylacetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-[(3,4-difluorophenyl)sulfanyl]-2-phenylacetic acid (CAS 1097125-23-9), molecular formula C14H10F2O2S and molecular weight 280.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, 2-[(3,4-difluorophenyl)sulfanyl]-2-phenylacetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 2-[(3,4-difluorophenyl)sulfanyl]-2-phenylacetic acid 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.
