Chemical Structure

Methyl 2-(methoxymethyl)-7-methyl-5-oxo-5H-chromeno[2,3-b]pyridine-3-carboxylate CAS 338751-33-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 2-(methoxymethyl)-7-methyl-5-oxo-5H-chromeno[2,3-b]pyridine-3-carboxylate.

CATO supplies Methyl 2-(methoxymethyl)-7-methyl-5-oxo-5H-chromeno[2,3-b]pyridine-3-carboxylate (CAS 338751-33-0), a certified reference material (molecular formula C17H15NO5, MW 313.30 g/mol) for analytical method development and quality control.

Structurally, Methyl 2-(methoxymethyl)-7-methyl-5-oxo-5H-chromeno[2,3-b]pyridine-3-carboxylate (C17H15NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 313.30 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures Methyl 2-(methoxymethyl)-7-methyl-5-oxo-5H-chromeno[2,3-b]pyridine-3-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
