(2-Chloro-4-fluorophenyl)(thiophen-3-yl)methanone CAS 898771-41-0

Description

Compared with other compounds in its class, the molecular weight of 240.68 g/mol gives (2-Chloro-4-fluorophenyl)(thiophen-3-yl)methanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (2-Chloro-4-fluorophenyl)(thiophen-3-yl)methanone (CAS 898771-41-0), a certified reference material (molecular formula C11H6ClFOS, MW 240.68 g/mol) for analytical method development and quality control.

Structurally, (2-Chloro-4-fluorophenyl)(thiophen-3-yl)methanone (C11H6ClFOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 240.68 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.

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.
