7-(2-(2,5-Dimethyl-1-(thiophen-2-ylmethyl)-1H-pyrrol-3-yl)-2-oxoethoxy)-2H-chromen-2-one CAS 869354-02-9

Description

The occurrence of 7-(2-(2,5-Dimethyl-1-(thiophen-2-ylmethyl)-1H-pyrrol-3-yl)-2-oxoethoxy)-2H-chromen-2-one is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 7-(2-(2,5-Dimethyl-1-(thiophen-2-ylmethyl)-1H-pyrrol-3-yl)-2-oxoethoxy)-2H-chromen-2-one (CAS 869354-02-9), a certified reference material (molecular formula C22H19NO4S, MW 393.46 g/mol) for analytical method development and quality control.

7-(2-(2,5-Dimethyl-1-(thiophen-2-ylmethyl)-1H-pyrrol-3-yl)-2-oxoethoxy)-2H-chromen-2-one (C22H19NO4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
