Chemical Structure

2-Bromo-5-fluoro-4-nitropyridine 1-oxide CAS 935534-40-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 236.98 g/mol gives 2-Bromo-5-fluoro-4-nitropyridine 1-oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Bromo-5-fluoro-4-nitropyridine 1-oxide (CAS 935534-40-0), a certified reference material (molecular formula C5H2BrFN2O3, MW 236.98 g/mol) for analytical method development and quality control.

The molecular framework of 2-Bromo-5-fluoro-4-nitropyridine 1-oxide (C5H2BrFN2O3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine 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. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 2-Bromo-5-fluoro-4-nitropyridine 1-oxide 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.
