Description

Compared with other compounds in its class, the molecular weight of 342.35 g/mol gives Methyl 6-amino-5-cyano-2-(2-methoxy-2-oxoethyl)-4-(4-methylphenyl)-4H-pyran-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Methyl 6-amino-5-cyano-2-(2-methoxy-2-oxoethyl)-4-(4-methylphenyl)-4H-pyran-3-carboxylate (CAS 547769-52-8), a certified reference material (molecular formula C18H18N2O5, MW 342.35 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Methyl 6-amino-5-cyano-2-(2-methoxy-2-oxoethyl)-4-(4-methylphenyl)-4H-pyran-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
