Ethyl 7-methoxy-8-methyl-2-oxo-2H-chromene-3-carboxylate CAS 855287-26-2

Description

The occurrence of Ethyl 7-methoxy-8-methyl-2-oxo-2H-chromene-3-carboxylate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ethyl 7-methoxy-8-methyl-2-oxo-2H-chromene-3-carboxylate (CAS 855287-26-2), a certified reference material (molecular formula C14H14O5, MW 262.26 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 7-methoxy-8-methyl-2-oxo-2H-chromene-3-carboxylate (C14H14O5) 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 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.
