Description

The occurrence of 2-Ethyl-8-fluoro-3-methyl-1,4-dihydroquinolin-4-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Ethyl-8-fluoro-3-methyl-1,4-dihydroquinolin-4-one (CAS 1343211-22-2), molecular formula C12H12FNO and molecular weight 205.23 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Ethyl-8-fluoro-3-methyl-1,4-dihydroquinolin-4-one (C12H12FNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 205.23 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2-Ethyl-8-fluoro-3-methyl-1,4-dihydroquinolin-4-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.
