(2E)-1-(4-Bromophenyl)-3-(thiophen-2-yl)prop-2-en-1-one CAS 2910-79-4

Description

Compared with other compounds in its class, the molecular weight of 293.18 g/mol gives (2E)-1-(4-Bromophenyl)-3-(thiophen-2-yl)prop-2-en-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(2E)-1-(4-Bromophenyl)-3-(thiophen-2-yl)prop-2-en-1-one (CAS 2910-79-4) is a high-purity analytical reference standard with the molecular formula C13H9BrOS and a molecular weight of 293.18 g/mol.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, (2E)-1-(4-Bromophenyl)-3-(thiophen-2-yl)prop-2-en-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 293.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
