Chemical Structure

1-((4-Fluorophenyl)thio)butan-2-one CAS 1249805-49-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 198.26 g/mol gives 1-((4-Fluorophenyl)thio)butan-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-((4-Fluorophenyl)thio)butan-2-one (CAS 1249805-49-9), a certified reference material (molecular formula C10H11FOS, MW 198.26 g/mol) for analytical method development and quality control.

Structurally, 1-((4-Fluorophenyl)thio)butan-2-one (C10H11FOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 198.26 g/mol, it falls into the medium-molecular-weight range. 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).

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), 1-((4-Fluorophenyl)thio)butan-2-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.
