Description

Compared with other compounds in its class, the molecular weight of 259.26 g/mol gives Ethyl 7-Acetyl-4-oxo-1,4-dihydroquinoline-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 7-Acetyl-4-oxo-1,4-dihydroquinoline-3-carboxylate (CAS 115172-91-3), molecular formula C14H13NO4 and molecular weight 259.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 7-Acetyl-4-oxo-1,4-dihydroquinoline-3-carboxylate (C14H13NO4) is characterized by a nitrogen-containing heterocyclic scaffold, 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 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 Ethyl 7-Acetyl-4-oxo-1,4-dihydroquinoline-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.
