Ethyl 8-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylate CAS 71082-34-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 8-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylate.

Ethyl 8-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylate (CAS 71082-34-3) is a high-purity analytical reference standard with the molecular formula C13H13NO4 and a molecular weight of 247.25 g/mol.

Based on its molecular formula C13H13NO4, Ethyl 8-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 247.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Ethyl 8-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylate 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.
