Methyl 1-(2-ethoxy-2-oxoethyl)-6-(4-methoxyphenyl)-3-methyl-1h-pyrazolo[3,4-b]pyridine-4-carboxylate CAS 1011399-57-7

Description

The occurrence of Methyl 1-(2-ethoxy-2-oxoethyl)-6-(4-methoxyphenyl)-3-methyl-1h-pyrazolo[3,4-b]pyridine-4-carboxylate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Methyl 1-(2-ethoxy-2-oxoethyl)-6-(4-methoxyphenyl)-3-methyl-1h-pyrazolo[3,4-b]pyridine-4-carboxylate (CAS 1011399-57-7), a certified reference material (molecular formula C20H21N3O5, MW 383.40 g/mol) for analytical method development and quality control.

The molecular framework of Methyl 1-(2-ethoxy-2-oxoethyl)-6-(4-methoxyphenyl)-3-methyl-1h-pyrazolo[3,4-b]pyridine-4-carboxylate (C20H21N3O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).

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.
