Chemical Structure
Description
The molecular framework of Ethyl 2-(6-((4-methyl-5-oxo-2,5-dihydrofuran-2-yl)oxy)-3-oxo-3H-xanthen-9-yl)benzoate (C27H20O7) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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 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).
Ethyl 2-(6-((4-methyl-5-oxo-2,5-dihydrofuran-2-yl)oxy)-3-oxo-3H-xanthen-9-yl)benzoate (CAS 1807549-00-3), molecular formula C27H20O7 and molecular weight 456.44 g/mol, is a CATO reference standard with documented purity and traceability.
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.
