4-[(1E)-3-(4-Chlorophenyl)-3-oxoprop-1-en-1-yl]phenyl thiophene-2-carboxylate CAS 331460-49-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 368.83 g/mol gives 4-[(1E)-3-(4-Chlorophenyl)-3-oxoprop-1-en-1-yl]phenyl thiophene-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-[(1E)-3-(4-Chlorophenyl)-3-oxoprop-1-en-1-yl]phenyl thiophene-2-carboxylate (CAS 331460-49-2) is a high-purity analytical reference standard with the molecular formula C20H13ClO3S and a molecular weight of 368.83 g/mol.

4-[(1E)-3-(4-Chlorophenyl)-3-oxoprop-1-en-1-yl]phenyl thiophene-2-carboxylate (C20H13ClO3S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
