(2e)-3-[5-(4-fluorophenyl)thiophen-2-yl]prop-2-enoic acid CAS 929975-30-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2e)-3-[5-(4-fluorophenyl)thiophen-2-yl]prop-2-enoic acid.

(2e)-3-[5-(4-fluorophenyl)thiophen-2-yl]prop-2-enoic acid (CAS 929975-30-4) is a high-purity analytical reference standard with the molecular formula C13H9FO2S and a molecular weight of 248.27 g/mol.

Based on its molecular formula C13H9FO2S, (2e)-3-[5-(4-fluorophenyl)thiophen-2-yl]prop-2-enoic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 248.27 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).

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.
