1-(5-Fluorothiophen-2-yl)ethan-1-one CAS 29669-44-1

Description

The occurrence of 1-(5-Fluorothiophen-2-yl)ethan-1-one is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(5-Fluorothiophen-2-yl)ethan-1-one (CAS 29669-44-1) is a high-purity analytical reference standard with the molecular formula C6H5FOS and a molecular weight of 144.17 g/mol.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 1-(5-Fluorothiophen-2-yl)ethan-1-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
