(5Z)-5-[(3-Fluorophenyl)methylidene]-4H,5H,6H-thieno[2,3-b]thiopyran-4-one CAS 1164519-83-8

Description

Based on its molecular formula C14H9FOS2, (5Z)-5-[(3-Fluorophenyl)methylidene]-4H,5H,6H-thieno[2,3-b]thiopyran-4-one contains sulfur-containing functionality, 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 276.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

(5Z)-5-[(3-Fluorophenyl)methylidene]-4H,5H,6H-thieno[2,3-b]thiopyran-4-one (CAS 1164519-83-8) is a high-purity analytical reference standard with the molecular formula C14H9FOS2 and a molecular weight of 276.35 g/mol.

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.
