1-(5-(3-Chlorophenyl)thiophen-2-yl)ethan-1-one CAS 855609-52-8

Description

Compared with other compounds in its class, the molecular weight of 236.72 g/mol gives 1-(5-(3-Chlorophenyl)thiophen-2-yl)ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(5-(3-Chlorophenyl)thiophen-2-yl)ethan-1-one (CAS 855609-52-8), molecular formula C12H9ClOS and molecular weight 236.72 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H9ClOS, 1-(5-(3-Chlorophenyl)thiophen-2-yl)ethan-1-one contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 236.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
