2-((4-Butyl-7-methyl-2-oxo-2h-chromen-5-yl)oxy)propanoic acid (CAS 843620-39-3) is a high-purity analytical reference standard with the molecular formula C17H20O5 and a molecular weight of 304.34 g/mol.
The molecular framework of 2-((4-Butyl-7-methyl-2-oxo-2h-chromen-5-yl)oxy)propanoic acid (C17H20O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
