6,8-Dimethoxy-9-(4-methoxyphenyl)-1H,3H,4H,9H-furo[3,4-b]quinolin-1-one CAS 1272756-30-5

Description

6,8-Dimethoxy-9-(4-methoxyphenyl)-1H,3H,4H,9H-furo[3,4-b]quinolin-1-one (CAS 1272756-30-5) is a high-purity analytical reference standard with the molecular formula C20H19NO5 and a molecular weight of 353.37 g/mol.

The molecular framework of 6,8-Dimethoxy-9-(4-methoxyphenyl)-1H,3H,4H,9H-furo[3,4-b]quinolin-1-one (C20H19NO5) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), 6,8-Dimethoxy-9-(4-methoxyphenyl)-1H,3H,4H,9H-furo[3,4-b]quinolin-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
