7-Hydroxy-3-(quinolin-7-yl)-4H-chromen-4-one CAS 97850-39-0

Description

The occurrence of 7-Hydroxy-3-(quinolin-7-yl)-4H-chromen-4-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Hydroxy-3-(quinolin-7-yl)-4H-chromen-4-one (CAS 97850-39-0) is a high-purity analytical reference standard with the molecular formula C18H11NO3 and a molecular weight of 289.28 g/mol.

The molecular framework of 7-Hydroxy-3-(quinolin-7-yl)-4H-chromen-4-one (C18H11NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 7-Hydroxy-3-(quinolin-7-yl)-4H-chromen-4-one 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.
