Chemical Structure
Description
(2E)-3-(4-Chlorophenyl)-1-(thiophen-2-yl)prop-2-en-1-one (CAS 79442-37-8), molecular formula C13H9ClOS and molecular weight 248.73 g/mol, is a CATO reference standard with documented purity and traceability.
(2E)-3-(4-Chlorophenyl)-1-(thiophen-2-yl)prop-2-en-1-one (C13H9ClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine 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.
As a certified reference material (CRM), (2E)-3-(4-Chlorophenyl)-1-(thiophen-2-yl)prop-2-en-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
