(2E)-1-(4-Bromophenyl)-3-(4-fluorophenyl)prop-2-en-1-one CAS 98991-32-3

Description

(2E)-1-(4-Bromophenyl)-3-(4-fluorophenyl)prop-2-en-1-one (CAS 98991-32-3), molecular formula C15H10BrFO and molecular weight 305.14 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, a polycyclic aromatic system, (2E)-1-(4-Bromophenyl)-3-(4-fluorophenyl)prop-2-en-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.14 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)-1-(4-Bromophenyl)-3-(4-fluorophenyl)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.
