Chemical Structure
Description
The molecular framework of 4-(6-methoxy-2-oxo-chromen-7-yl)oxy-4-oxo-butanoic acid (C14H20O7) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 4-(6-methoxy-2-oxo-chromen-7-yl)oxy-4-oxo-butanoic acid (CAS 2737330-67-3), a certified reference material (molecular formula C14H20O7, MW 300.30 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
