Chemical Structure
Description
(3e)-4-(4-Bromophenyl)but-3-enoic acid (CAS 184360-96-1), molecular formula C10H9BrO2 and molecular weight 241.08 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H9BrO2, (3e)-4-(4-Bromophenyl)but-3-enoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 241.08 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.
As a certified reference material (CRM), (3e)-4-(4-Bromophenyl)but-3-enoic acid 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.
