Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2E)-1-(3-Bromophenyl)-3-(2,4-dimethoxyphenyl)prop-2-en-1-one.
CATO supplies (2E)-1-(3-Bromophenyl)-3-(2,4-dimethoxyphenyl)prop-2-en-1-one (CAS 219488-03-6), a certified reference material (molecular formula C17H15BrO3, MW 347.20 g/mol) for analytical method development and quality control.
(2E)-1-(3-Bromophenyl)-3-(2,4-dimethoxyphenyl)prop-2-en-1-one (C17H15BrO3) contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
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.
