(2E)-1-(2,4-Dimethylphenyl)-3-(thiophen-2-yl)prop-2-en-1-one CAS 1345959-95-6

Description

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.

(2E)-1-(2,4-Dimethylphenyl)-3-(thiophen-2-yl)prop-2-en-1-one (CAS 1345959-95-6) is a high-purity analytical reference standard with the molecular formula C15H14OS and a molecular weight of 242.34 g/mol.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (2E)-1-(2,4-Dimethylphenyl)-3-(thiophen-2-yl)prop-2-en-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 242.34 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).

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.
