Chemical Structure
Description
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.
CATO supplies (2E)-3-(3-Bromophenyl)-1-(4-methylphenyl)prop-2-en-1-one (CAS 1047680-88-5), a certified reference material (molecular formula C16H13BrO, MW 301.18 g/mol) for analytical method development and quality control.
(2E)-3-(3-Bromophenyl)-1-(4-methylphenyl)prop-2-en-1-one (C16H13BrO) contains a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
