Chemical Structure
Description
(2E)-3-(4-Chlorophenyl)-1-(2,4-dimethylphenyl)prop-2-en-1-one (CAS 284665-99-2), molecular formula C17H15ClO and molecular weight 270.75 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution, (2E)-3-(4-Chlorophenyl)-1-(2,4-dimethylphenyl)prop-2-en-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 270.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), (2E)-3-(4-Chlorophenyl)-1-(2,4-dimethylphenyl)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.
