(E)-1-(4-chlorophenyl)-3-(5-(2-nitrophenyl)furan-2-yl)prop-2-en-1-one (C19H12ClNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
(E)-1-(4-chlorophenyl)-3-(5-(2-nitrophenyl)furan-2-yl)prop-2-en-1-one (CAS 299954-35-1) is a high-purity analytical reference standard with the molecular formula C19H12ClNO4 and a molecular weight of 353.76 g/mol.
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.
