Description

Compared with other compounds in its class, the molecular weight of 236.16 g/mol gives 5-Fluoro-8-nitroquinoline-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Fluoro-8-nitroquinoline-2-carboxylic acid (CAS 1420791-65-6), molecular formula C10H5FN2O4 and molecular weight 236.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Fluoro-8-nitroquinoline-2-carboxylic acid (C10H5FN2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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. 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.

CATO manufactures 5-Fluoro-8-nitroquinoline-2-carboxylic acid 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.
