Description

Compared with other compounds in its class, the molecular weight of 348.37 g/mol gives Methyl 3-{5-[(1E)-2-acetyl-3-ethoxy-3-oxoprop-1-en-1-yl]furan-2-yl}thiophene-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Methyl 3-{5-[(1E)-2-acetyl-3-ethoxy-3-oxoprop-1-en-1-yl]furan-2-yl}thiophene-2-carboxylate (CAS 241488-49-3), a certified reference material (molecular formula C17H16O6S, MW 348.37 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, Methyl 3-{5-[(1E)-2-acetyl-3-ethoxy-3-oxoprop-1-en-1-yl]furan-2-yl}thiophene-2-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.37 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.
