1-[4-(5-bromothiophen-2-yl)phenyl]ethan-1-one CAS 929972-12-3

Description

Compared with other compounds in its class, the molecular weight of 281.17 g/mol gives 1-[4-(5-bromothiophen-2-yl)phenyl]ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-[4-(5-bromothiophen-2-yl)phenyl]ethan-1-one (CAS 929972-12-3), molecular formula C12H9BrOS and molecular weight 281.17 g/mol, is a CATO reference standard with documented purity and traceability.

1-[4-(5-bromothiophen-2-yl)phenyl]ethan-1-one (C12H9BrOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
