3-Acetyl-2,7-dimethyl-5H-chromeno[2,3-b]pyridin-5-one CAS 67867-48-5

Description

The occurrence of 3-Acetyl-2,7-dimethyl-5H-chromeno[2,3-b]pyridin-5-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Acetyl-2,7-dimethyl-5H-chromeno[2,3-b]pyridin-5-one (CAS 67867-48-5) is a high-purity analytical reference standard with the molecular formula C16H13NO3 and a molecular weight of 267.28 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3-Acetyl-2,7-dimethyl-5H-chromeno[2,3-b]pyridin-5-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 267.28 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.
