Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Methyl 6-amino-5-cyano-4-(4-cyanophenyl)-2-(2-methoxy-2-oxoethyl)-4H-pyran-3-carboxylate (CAS 865660-39-5) is a high-purity analytical reference standard with the molecular formula C18H15N3O5 and a molecular weight of 353.33 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Methyl 6-amino-5-cyano-4-(4-cyanophenyl)-2-(2-methoxy-2-oxoethyl)-4H-pyran-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 353.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
